Introduction to Algorithms and Data Structures (DSA):

Data Structures and Algorithms are foundational concepts in computer science that play a crucial role in solving computational problems efficiently. Data structures are organized and stored in formats to enable efficient data manipulation and retrieval. They provide a way to organize and store data so that operations can be performed efficiently. Some of the common data structures that every developer should know are Arrays, Linked List, Stack, Queue, Trees, Graphs, etc. Algorithms are step-by-step procedures or formulas for solving specific problems. They are a sequence of well-defined, unambiguous instructions designed to perform a specific task or solve a particular problem. Some of the common algorithms that every developer should know are Searching Algorithms, Sorting Algorithms, Graph Algorithms, Dynamic Programming, Divide and Conquer, etc....

Bitwise Algorithms:

The Bitwise Algorithms is used to perform operations at the bit-level or to manipulate bits in different ways. The bitwise operations are found to be much faster and are sometimes used to improve the efficiency of a program. Bitwise algorithms involve manipulating individual bits of binary representations of numbers to perform operations efficiently. These algorithms utilize bitwise operators like AND, OR, XOR, shift operators, etc., to solve problems related to tasks such as setting, clearing, or toggling specific bits, checking if a number is even or odd, swapping values without using a temporary variable, and more....
