They are used to store and manipulate text-based data, and can be manipulated using various library functions such as strcpy(), strcat(), strlen(), and more. Strings are mutable, meaning their content can be changed. They are an essential part of coding in C. 28. Python - Sort Python Dictionaries by Key or Value Python is an easy-to-use, powerful programming language. It allows developers to quickly create programs by using simple syntax and data structures such as dictionaries. Dictionaries in Python are unordered collections of data, but they can be sorted by key or value for easy access. With Python, developers can quickly create programs that are both efficient and organized. 29. Change Plot Size in Matplotlib Python Matplotlib Python is a powerful plotting library that can be used to create a variety of graphs and charts. It allows you to change the size of the plot by setting the figsize parameter of the figure object. This can be done by calling the figure() function and passing in the figsize parameter to set the size of the plot. You can also change the size of the plot by changing the aspect ratio of the plot. This can be done by setting the aspect parameter of the plot. By using these parameters you can easily customize the size of the plot to the desired size. 30. Convert Double to Integer in Java Java provides a convenient way to convert from a double to an integer. The method used is the "Math.round()" function, which takes a double as its argument and returns the nearest integer. The result of the conversion is an int value, with any decimal places truncated. The conversion is straightforward and requires no additional steps. 31. Modulo or Remainder Operator in Java The Modulo or Remainder Operator in Java is used to divide two numbers and gives the remainder of the division. It uses the percentage (%) symbol and is useful for finding remainders and determining whether a number is even or odd. It can also be used for looping, determining factors of a number, and finding out if a number is divisible by another number. 32. Difference between BFS and DFS BFS and DFS are two algorithms used in graph traversal. BFS stands for Breadth-First Search and DFS stands for Depth-First Search. BFS uses a queue to explore the nodes, while DFS uses a stack. BFS visits all the nodes before exploring the next level, while DFS explores one branch fully before moving onto the next one. BFS is better for finding the shortest path to a goal, while DFS is more suitable for solving puzzle-like problems. 33. Java util HashMap in Java with Examples HashMap is a powerful data structure in Java that is used to store key-value pairs. It allows constant time complexity for operations like insertion, deletion, and retrieval. It is not synchronized and can be used in multi-threaded environment. HashMap works on the principle of hashing which makes it efficient in terms of performance. It can be used to store and retrieve data quickly. Examples of using HashMap include storing user data in a database, caching frequently used data, mapping keys to values, and more. 34. SQL Order By SQL Order By is a powerful command used to sort the data in a relational database. It organizes information in ascending or descending order and can be used in combination with other SQL clauses. It is a great way to quickly query and analyze data sets to uncover trends and insights. Order By is an essential tool for data analysis and manipulation. 35. Python random.sample() Function The Python random.sample() function is a useful tool for randomly selecting elements from a sequence, such as a list or tuple. It allows you to select a number of unique items from a given sequence, ensuring that no elements are repeated. This function is especially useful for generating random numbers when performing statistical analysis or for creating random permutations for gaming purposes. 36. Docker Copy Instruction Docker is an open-source software platform that helps developers to create, deploy, and run applications quickly and efficiently. It allows developers to package and containerize applications, making them easier to manage and deploy. Docker also provides an isolated environment for applications, allowing them to run in their own isolated space. With Docker, developers can build, ship, and run applications faster and more efficiently. 37. Ruby String Split Method with Examples The Ruby String Split Method is a powerful tool for manipulating strings. It allows you to break a string into separate parts, or substrings, based on a given delimiter. For example, you can use it to split a sentence into words, or to split a sentence into individual letters. Examples of using the split method include splitting a sentence into words, or splitting a comma-separated string into its separate values. 38. Mongoose FindOne Function Mongoose FindOne Function is a powerful tool for querying MongoDB documents. It allows you to retrieve a single document from a MongoDB collection that matches a given set of criteria. It is a fast and efficient way to query for a single document from a large collection and can be used for various tasks such as locating a particular document or verifying the existence of a particular document. 39. How To Reduce Latency Reducing latency can be a challenge, but it's important in order to ensure smooth, reliable performance of applications and services. This guide provides steps for optimizing latency, including identifying the causes of latency and using tools to measure and reduce it. With the right strategies, you can significantly reduce latency and improve application performance. 40. JavaScript Array splice() Method The JavaScript Array splice() method is a powerful tool for manipulating arrays. It can add, remove, and replace elements in an array, and can insert elements into an array at a specified position. It also returns the removed elements as an array.
