Priority Queue in CPP STL The Priority Queue in the CPP Standard Template Library (STL) is a container adaptor that provides an interface for inserting and extracting elements in a particular order. It is a type of queue where elements are always retrieved in order of highest priority. The elements are ordered according to a comparison function, or by providing a comparison functor. Priority Queue also supports various operations such as push, pop, peek, and size. 27. Python - Read CSV using Pandas read_csv() Python is a powerful and versatile programming language that can be used for data analysis and manipulation. One of the most popular methods for reading data stored in CSV files is the Pandas library's read_csv() function. This function allows you to quickly and easily load data from a CSV file and store it in a Pandas dataframe, making it simple to analyze and manipulate data. With read_csv() you can easily read data from any CSV file into Python. 28. Function Pointer in C Function pointers in C are pointers that point to a function instead of a value. They are used to pass functions as arguments to other functions, access and modify functions, and call functions indirectly. Function pointers provide a level of indirection, allowing code to be written in a more flexible and maintainable way. 29. Graph Data Structure and Algorithms Graph Data Structures and Algorithms are powerful tools used to represent and analyze complex relationships between objects. They are used to store and traverse data in an efficient manner, and can be used to solve a variety of problems such as finding the shortest path between two points or determining the most efficient route for a delivery truck. Graph algorithms can also be used to analyze networks, optimize resources, and detect patterns. 30. Check Multiple Conditions in If Statement (Python) If statements are a powerful way to check multiple conditions in Python. They allow us to control program flow and make decisions based on certain criteria. Syntactically, an if statement consists of a boolean expression followed by one or more statements to execute when the boolean expression evaluates to True. In Python, we can use the and, or, and not operators to combine multiple boolean expressions and form complex conditions. This allows us to check multiple conditions in a single if statement. 31. Python Initialize Empty Array of Given Length Python is a powerful, versatile programming language that can be used to create a wide variety of applications. It is easy to learn and has a friendly, intuitive syntax. In Python, it is possible to create and initialize an empty array of a given length using the syntax array = [None] * length. This array can then be populated with data as needed. 32. Java util.Random nextInt() in Java Java util.Random nextInt() is a method of the Random class that returns a pseudorandom integer between 0 (inclusive) and the specified value (exclusive). It is a powerful tool for generating random values in Java, and is often used in a wide range of applications, from game programming to cryptography. 33. Python String Concatenation Python String Concatenation is a powerful way to combine strings. It enables us to join individual characters, words, and even entire sentences together to form a single, larger string. It is an essential tool for text manipulation, simplifying complex operations and providing users with more control over their data. With Python String Concatenation, we can quickly and easily create meaningful, organized strings. 34. Sort in Python Sort is a core Python function used to organize data in either ascending or descending order. It works on both iterable objects such as lists, tuples, strings, and dictionaries, and can be used to arrange numerical or alphabetical values. It is often used in combination with other functions like lambda to customize the sorting criteria. With the power of Sort, data can be quickly and easily ordered in any Python project. 35. Python Try Except Python is a powerful, versatile programming language. It allows you to write code quickly and easily, and is great for beginners. With Try Except statements, you can control how your code behaves when errors occur. This feature of Python helps you anticipate and handle errors gracefully, making debugging and troubleshooting much easier. Try Except statements allow you to separate cleanly the code that handles errors from the code that performs the intended action. This makes it easier to pinpoint the source of the problem and make corrections. 36. Declare an Empty List in Python Python provides a simple way to declare an empty list. By using the list() constructor, an empty list can be easily created. An empty list can be used to store items of any data type, such as strings, numbers and booleans. To declare an empty list in Python, simply type list() and assign it to a variable. 37. Bash Scripting - If Statement Bash Scripting is a powerful tool for automating tasks on Linux systems. With it, you can write scripts to perform complex tasks with just a few lines of code. One of the most important concepts in Bash Scripting is the If Statement, which allows you to make decisions in your scripts. If Statements enable you to check values and then take different actions based on the result. Learning to use If Statements will help you create more useful and powerful scripts. 38. Unordered_map in CPP STL Unordered_map is a part of the C++ Standard Template Library (STL). It is a data structure that stores key-value pairs, and provides efficient insertion, search, and deletion operations. It is implemented as a hash table and offers constant time complexity for retrieval and insertion of elements. Unordered_map is an unordered associative container, meaning that the order of elements is not preserved. Its flexibility and efficiency make it a popular choice for solving many programming problems. 39. Print Lists in Python - 4 Different Ways Printing lists in Python is a simple way to show all the items in a list. There are four main ways to print a list. The most common way is to use a for loop to iterate through each item and print it. Additionally, you can use list comprehension, the join method, and the pprint module. Each method has its own advantages and disadvantages, so choose the one that best meets your needs. 40. What is Linked List Linked List is a data structure used in computer programming that consists of a sequence of nodes linked together by pointers. Each node contains a data element and a reference to the next node in the list. Linked Lists are useful for storing and manipulating data in a more efficient way than other data structures such as arrays.
