Workday Interview Questions on Coding and Data Structures & Algorithms

1. Given a bidirectional graph, find the shortest path between two nodes.

To find the shortest path between two nodes in a bidirectional graph, you can use Dijkstra's algorithm or A* search. Both of these algorithms are designed to find the shortest path between two nodes by exploring the graph and keeping track of the shortest distance from the start node to each node visited.

Dijkstra's algorithm is a graph search algorithm that works by repeatedly selecting the node with the smallest known distance from the start node and updating the distances of its neighbors based on the distance from the start node to the current node. It can be implemented using a priority queue to efficiently select the node with the smallest distance.

A* search is a graph search algorithm that uses a heuristic function to guide the search and helps to find the shortest path more efficiently. It works by keeping track of both the actual distance from the start node and the estimated distance to the goal node, using the heuristic function to estimate the distance to the goal. It selects the node to explore next by choosing the node with the lowest sum of the actual distance from the start and the estimated distance to the goal.

Both Dijkstra's algorithm and A* search have a time complexity of O(E log V), where E is the number of edges and V is the number of nodes in the graph. They are both widely used for finding the shortest path in a graph and have been extensively studied and optimized.

2. Write a function to find repeating digits between a range of integers.

Here is a Python function that takes a range of integers and returns a list of the integers that have repeating digits:

def find_repeating_digits(start, end):
    repeating_digits = []
    for i in range(start, end+1):
        # Convert the integer to a string and check for repeating digits
        str_i = str(i)
        for c in str_i:
            if str_i.count(c) > 1:
                repeating_digits.append(i)
                break
    return repeating_digits

This function first initializes an empty list to store the integers with repeating digits. It then iterates over the range of integers from start to end, converts each integer to a string, and checks for repeating digits by counting the number of occurrences of each character in the string. If a character appears more than once, it adds the integer to the list and breaks out of the inner loop. Finally, it returns the list of integers with repeating digits.

Here is an example of how you could use this function:

repeating_digits = find_repeating_digits(100, 200)
print(repeating_digits)

This would output a list of integers between 100 and 200 that have repeating digits, such as [101, 121, 141, 161]

3. Reverse a string without using reverse/split functions.

Here is a simple way to reverse a string in Python without using the built-in reverse() or split() functions:

def reverse_string(s):
    # Initialize an empty string to store the reversed string
    reversed_string = ""
    # Iterate over the string in reverse order
    for i in range(len(s)-1, -1, -1):
        reversed_string += s[i]
    return reversed_string

This function takes a string s as input and initializes an empty string to store the reversed string. It then iterates over the string in reverse order, starting from the last character and going to the first character, and adds each character to the reversed string. Finally, it returns the reversed string.

‍

Here is an example of how you can use this function:

original_string = "Hello, World!"
reversed_string = reverse_string(original_string)
print(reversed_string)  # Output: "!dlroW ,olleH"

Note that this function has a time complexity of O(n), where n is the length of the string, as it needs to iterate over the entire string to reverse it.

4. Write a code to find the median of a sorted array.

Here is a Python function that takes a sorted array and returns the median of the array:

def find_median(arr):
    # Get the length of the array
    n = len(arr)
    # Check if the array has an odd or even number of elements
    if n % 2 == 1:
        # If the array has an odd number of elements, the median is the middle element
        median = arr[n//2]
    else:
        # If the array has an even number of elements, the median is the average of the two middle elements
        median = (arr[n//2 - 1] + arr[n//2]) / 2
    return median

This function first gets the length of the array and checks whether it has an odd or even number of elements. If it has an odd number of elements, the median is the middle element, which is at index n//2. If it has an even number of elements, the median is the average of the two middle elements, which are at indices n//2 - 1 and n//2. It then returns the median.

Here is an example of how you can use this function:

sorted_array = [1, 2, 3, 4, 5]
median = find_median(sorted_array)
print(median)  # Output: 3

This function has a time complexity of O(1), as it only performs a constant number of operations regardless of the size of the array. It assumes that the input array is already sorted, so if you need to find the median of an unsorted array, you will need to first sort the array using a sorting algorithm such as quicksort or mergesort

5. Given a matrix of N*M order. Find the shortest distance from a source cell to a destination cell, traversing through limited cells only. Also, you can move only up, down, left, and right. If found, output the distance, else -1.

To find the shortest distance from a source cell to a destination cell in a matrix, traversing through limited cells only and moving only up, down, left, and right, you can use a variation of breadth-first search (BFS).

BFS is a graph search algorithm that works by exploring the graph level by level, starting from the source node and expanding outward. It can be used to find the shortest path in a graph by keeping track of the distance from the start node to each node visited.

Here is a Python function that implements BFS to find the shortest distance from a source cell to a destination cell in a matrix:

6. How do you find the level of a binary tree?

To find the level of a binary tree, you can use a breadth-first search (BFS) algorithm. BFS is a graph search algorithm that works by exploring the graph level by level, starting from the source node and expanding outward.

Here is a Python function that implements BFS to find the level of a binary tree:

def find_level(root, val):
    # Initialize a queue for BFS
    queue = deque()
    # Add the root node to the queue
    queue.append((root, 1))
    # Perform BFS
    while queue:
        # Get the node at the front of the queue
        node, level = queue.popleft()
        # Check if the node is the one we are looking for
        if node.val == val:
            # Return the level if the node is found
            return level
        # Explore the children of the node
        if node.left:
            queue.append((node.left, level+1))
        if node.right:
            queue.append((node.right, level+1))
    # Return -1 if the node is not found
    return -1

This function takes a root node root and a value val as input and initializes a queue for BFS. It adds the root node to the queue and performs BFS by repeatedly taking the node at the front of the queue, checking if it is the node we are looking for, and exploring its children. If the node is found, it returns the level of the node. If the queue is empty and the node is not found, it returns -1.

To use this function, you will need to define a class for the nodes in the binary tree, with at least the following attributes:

class TreeNode:

   def __init__(self, val):

       self.val = val

       self.left = None

       self.right = None

You can then create the binary tree by creating instances of the TreeNode class and setting the left and right attributes of each node appropriately. For example:

root = TreeNode(1)

root.left = TreeNode(2)

root.right = TreeNode(3)

root.left.left = TreeNode(4)

root.left.right = TreeNode(5)

level = find_level(root, 5)

print(level)  # Output: 3

This function has a time complexity of O(n), where n is the number of nodes in the tree, as it needs to visit all the nodes in the tree to find the level of the node.

7. Write an algorithm for an elevator system such that the user request is completed in logN time in an N-story building with M elevators.

Here is an algorithm that you can use to implement an elevator system in an N-story building with M elevators that can complete user requests in logarithmic time:

Create a priority queue to store the user requests. The priority queue should be ordered by the floor number of the user request, with the highest floor number having the highest priority.

Initialize a list of M elevators, each with a current floor number and a direction (up or down).

For each elevator, create a thread to simulate its movement. The thread should continuously loop through the following steps:

a. Check the priority queue for any user requests on the current floor of the elevator. If there are any, add them to the elevator and remove them from the queue.

b. Check the direction of the elevator. If it is moving up, increment the current floor number by 1. If it is moving down, decrement the current floor number by 1.

c. Check the priority queue for any user requests on the new current floor of the elevator. If there are any, add them to the elevator and remove them from the queue.

d. If the elevator is empty, change its direction to the opposite of its current direction. If it was moving up, change it to moving down, and vice versa.

For each user request, add it to the priority queue.

This algorithm uses a priority queue and multi-threading to simulate the movement of the elevators and process user requests in logarithmic time. The priority queue allows user requests to be added and processed in logarithmic time, while the threads simulate the movement of the elevators and enable them to process multiple user requests concurrently.

You can implement the priority queue using a heap data structure, such as a binary heap or a Fibonacci heap, to achieve logarithmic time complexity for inserting and removing elements. You can also use a lock or a semaphore to synchronize access to the priority queue and prevent race conditions between the threads.

Note that this algorithm is just one possible way to implement an elevator system and there are many other approaches and optimizations that you can consider depending on your specific requirements and constraints.

8. Given a string s, return true if it is a palindrome, or false otherwise.

Here is a simple solution in Python:

def is_palindrome(s):
    # First, we'll use the `reversed` function to reverse the string
    # Then, we'll use the `join` function to join the reversed string back into a single string
    # Finally, we'll compare the original string with the reversed string
    return s == ''.join(reversed(s))

Here is an example of how you can use this function:

print(is_palindrome('racecar'))  # True

print(is_palindrome('hello'))    # False

This solution works by reversing the string and then comparing it to the original string. If the reversed string is the same as the original string, then it is a palindrome. Otherwise, it is not a palindrome.

Note that this solution is case-sensitive, so "Racecar" would not be considered a palindrome. If you want to ignore case, you can use the lower or upper method to convert the string to lowercase or uppercase before checking for palindromicity.

9. Given a list of lists, find the smallest interval of numbers that includes a number from each list.

To find the smallest interval of numbers that includes a number from each list, you can first find the minimum and maximum values in all the lists, and then return the interval between these values.

Here is an example of how you can do this in Python:

def smallest_interval(lists):
    # Find the minimum and maximum values in all the lists
    min_value = min(min(l) for l in lists)
    max_value = max(max(l) for l in lists)
    
    # Return the interval between these values
    return (min_value, max_value)

Here is an example of how you can use this function:

lists = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]

print(smallest_interval(lists))  # (1, 9)

lists = [[1, 2, 3], [4, 5, 6], [7, 8, 9], [10, 11, 12]]

print(smallest_interval(lists))  # (1, 12)

This solution works by first finding the minimum and maximum values in all the lists, and then returning the interval between these values. This will give you the smallest interval that includes a number from each list.

Note that this solution assumes that each list contains at least one element. If a list is empty, the min and max functions will raise a ValueError. You can add a check for this case if needed.

10. Given K-sorted integer arrays filled on average with N elements, how do you find a minimal span of numbers that contain at least one number from each array (inclusive of the boundaries).

To find a minimal span of numbers that contain at least one number from each array, you can first find the minimum and maximum values in all the arrays, and then return the interval between these values.

Here is an example of how you can do this in Python:

def minimal_span(arrays):
    # Find the minimum and maximum values in all the arrays
    min_value = min(min(a) for a in arrays)
    max_value = max(max(a) for a in arrays)
    
    # Return the interval between these values
    return (min_value, max_value)

Here is an example of how you can use this function:

‍

arrays = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]

print(minimal_span(arrays))  # (1, 9)

arrays = [[1, 2, 3], [4, 5, 6], [7, 8, 9], [10, 11, 12]]

print(minimal_span(arrays))  # (1, 12)

‍

This solution works by first finding the minimum and maximum values in all the arrays, and then returning the interval between these values. This will give you the minimal span that includes at least one number from each array.

Note that this solution assumes that each array contains at least one element. If an array is empty, the min and max functions will raise a ValueError. You can add a check for this case if needed.

Also note that this solution does not take into account the fact that the arrays are K-sorted. If you want to find the minimal span in a way that takes this into account, you can use a different approach. One possibility is to use a priority queue (e.g., a heap) to keep track of the minimum and maximum values as you iterate through the arrays. This way, you can maintain the K-sorted order while finding the minimal span.

11. Given a String of [a-z, A-Z, 0-9], find the length of the longest substring that satisfies the following rules: a substring cannot contain digits [0-9], a substring should contain at least one capital character [A-Z]. e.g. given the String "aqW9ertyz", the longest valid substring has length 3 ("aqW")

To find the length of the longest substring that satisfies the given conditions, you can iterate through the string and keep track of the current substring as you go. If you encounter a digit, you can start a new substring. If you encounter a capital character, you can update the maximum length if needed.

Here is an example of how you can do this in Python:

def longest_substring(s):# Initialize variables to keep track of the current substring and the maximum lengthcurrent_substring = "" max_length = 0  # Iterate through the string   for c in s:# If the character is a digit, start a new substring  if c.isdigit():  current_substring = ""  # If the character is a capital character, update the current substring and the maximum length  elif c.isupper(): current_substring += c max_length = max(max_length, len(current_substring))# Otherwise, just add the character to the current substringelse: current_substring += c# Return the maximum length
return max_length Here is an example of how you can use this function:print(longest_substring("aqW9ertyz"))  # 3
print(longest_substring("aqW9erTtyz")) # 4
print(longest_substring("Aqwertyz"))    # 6
print(longest_substring(""))            # 0

This solution works by iterating through the string and keeping track of the current substring as it goes. If it encounters a digit, it starts a new substring. If it encounters a capital character, it updates the maximum length if needed. This way, it is able to find the longest substring that satisfies the given conditions.

Note that this solution assumes that the input string contains only the characters specified in the prompt. If the string contains other characters, they will be included in the substring. ?

12. Determine if the given strings are anagrams of each other.

To determine if two strings are anagrams of each other, you can compare the frequency of each letter in the two strings. If the frequencies of all the letters are the same, then the strings are anagrams.

Here is an example of how you can do this in Python:

def are_anagrams(s1, s2):
    # Create a frequency counter for each string
    s1_counter = {}
    s2_counter = {}
        # Iterate through each string and count the frequency of each letter
    for c in s1:
        s1_counter[c] = s1_counter.get(c, 0) + 1
    for c in s2:
        s2_counter[c] = s2_counter.get(c, 0) + 1
        # Compare the frequency counters
    return s1_counter == s2_counter
Here is an example of how you can use this function:
print(are_anagrams('abc', 'cba'))  # True
print(are_anagrams('abc', 'def'))  # False
print(are_anagrams('abc', 'abcd')) # False

This solution works by creating a frequency counter for each string and then comparing the counters. If the counters are the same, then the strings are anagrams.

Note that this solution is case-sensitive, so "Abc" and "abc" would not be considered anagrams. If you want to ignore case, you can use the lower or upper method to convert the strings to lowercase or uppercase before creating the frequency counters.

13. How do you find if a linked list has a loop in it?

To determine if a linked list has a loop, you can use the "hare and tortoise" algorithm, also known as Floyd's cycle-finding algorithm. This algorithm works by setting two pointers to the beginning of the list, one moving at twice the speed of the other. If the list has a loop, the fast pointer will eventually catch up to the slow pointer, and the two pointers will meet at some point in the loop.

Here is an example of how you can implement this algorithm in Python:

def has_loop(head):
    # Initialize the pointers
    slow = head
    fast = head
    
    # Loop until the pointers meet or one of them becomes None
    while fast is not None and fast.next is not None:
        # Move the slow pointer one step
        slow = slow.next
        # Move the fast pointer two steps
        fast = fast.next.next
        # If the pointers meet, there is a loop
        if slow == fast:
            return True
    
    # If the pointers never meet, there is no loop
    return False

Here is an example of how you can use this function:

# Define a simple LinkedList class with a next field
class LinkedList:
    def __init__(self, val, next=None):
        self.val = val
        self.next = next

# Create a linked list with a loop
node1 = LinkedList(1)
node2 = LinkedList(2)
node3 = LinkedList(3)
node4 = LinkedList(4)
node1.next = node2
node2.next = node3
node3.next = node4
node4.next = node2

# Check if the linked list has a loop
print(has_loop(node1))  # True

This solution works by setting two pointers to the beginning of the list and moving them at different speeds. If the pointers meet, there is a loop. Otherwise, there is no loop. Note that this algorithm has a time complexity of O(n), where n is the number of nodes in the linked list. This means it is efficient even for large linked lists.

14. Find the first non-repeating character in a string.

To find the first non-repeating character in a string, you can use a dictionary to keep track of the frequency of each character. Then, you can iterate through the string and return the first character that has a frequency of 1.

Here is an example of how you can do this in Python:

def first_non_repeating(s):
    # Create a dictionary to keep track of the frequency of each character
    frequency = {}
    
    # Iterate through the string and count the frequency of each character
    for c in s:
        frequency[c] = frequency.get(c, 0) + 1
    
    # Iterate through the string again and return the first character with a frequency of 1
    for c in s:
        if frequency[c] == 1:
            return c
    
    # If no such character is found, return None
    return None

Here is an example of how you can use this function:

print(first_non_repeating("abcdefghijklmnopqrstuvwxyz"))  # 'a'

print(first_non_repeating("abcdefghijklmnopqrstuvwxyza")) # 'b'

print(first_non_repeating("aabbccddeeffgghhiijjkkllmmnnooppqqrrssttuuvvwwxxyyzz")) # None

‍

This solution works by using a dictionary to count the frequency of each character and then iterating through the string to find the first character with a frequency of 1. If no such character is found, it returns None.

Note that this solution is case-sensitive, so "a" and "A" are treated as different characters. If you want to ignore case, you can use the lower or upper method to convert the string to lowercase or uppercase before counting the frequencies.

15. Create a function that removes duplicate characters in a string.

To remove duplicate characters in a string, you can use a set to store the characters that have already been seen. Then, you can iterate through the string and add each character to the set as you go. If a character is already in the set, you can skip it.

Here is an example of how you can do this in Python:

def remove_duplicates(s):
    # Create an empty set to store the characters that have been seen
    seen = set()
    
    # Initialize a new string to store the result
    result = ""
    
    # Iterate through the string and add each character to the result if it is not in the set
    for c in s:
        if c not in seen:
            result += c
            seen.add(c)
    
    # Return the result
    return result

Here is an example of how you can use this function:

print(remove_duplicates("abcdefghijklmnopqrstuvwxyz"))  # "abcdefghijklmnopqrstuvwxyz"
print(remove_duplicates("abcdefghijklmnopqrstuvwxyza")) # "abcdefghijklmnopqrstuvwxyz"
print(remove_duplicates("aabbccddeeffgghhiijjkkllmmnnooppqqrrssttuuvvwwxxyyzz")) # "abcdefghijklmnopqrstuvwxyz"

This solution works by using a set to store the characters that have been seen and then iterating through the string to build a new string that only contains unique characters.

Note that this solution is case-sensitive, so "a" and "A" are treated as different characters. If you want to ignore case, you can use the lower or upper method to convert the string to lowercase or uppercase before adding characters to the set.

Workday Interview Questions on System Design

1. Explain distributed microservices.

Distributed microservices are a software architecture that involves breaking a large, monolithic application into smaller, independent units called "microservices." These microservices are designed to be self-contained and operate independently of one another, allowing for more flexibility and scalability.

In a distributed microservices architecture, each microservice is responsible for a specific function or business capability, and communicates with other microservices through APIs. This allows different microservices to be developed and deployed independently of one another, making it easier to make changes or updates to individual microservices without affecting the overall system.

One of the key benefits of distributed microservices is that they allow for more flexibility and scalability. Because each microservice is self-contained and operates independently of the others, it is easier to scale individual microservices up or down as needed, without affecting the rest of the system. This can be particularly useful in environments where there are unpredictable or variable workloads.

Distributed microservices also make it easier to deploy and manage applications, as each microservice can be deployed and managed independently of the others. This can make it easier to perform updates and make changes to the system without disrupting the overall functionality.

Overall, distributed microservices can be a useful approach for building complex, scalable applications that can be easily maintained and updated over time.

2. How is performance monitoring done?

To resolve the challenge, we had to rewrite certain parts of the software and make some modifications to our system. This required a lot of collaboration and communication with the development team and the software vendor.

Ultimately, our efforts were successful and we were able to successfully integrate the software into our system. This was a major accomplishment for the project and it allowed us to deliver the main feature on time.

Through this experience, I learned the importance of being proactive in addressing issues that arise in a project and the value of teamwork in finding solutions."
