To learn DSA in a simple ways to start with the basics like arrays and simple sorting algorithms. Use visual aids and tutorials from different platforms and YouTube channels in your comfortable language. Practice by writing code for simple structures like linked lists and trees. To do this you can solve problems on LeetCode and HackerRank. There are different categories of questions from easy to hard, go with the easy ones first. Understand the question, find out the logic and try to create the algorithm for it. When having doubts do not check for the solution, check out for similar questions and look into the code. Then try again you will definitely be able to make another step forward in solving.
Understanding structures in C is crucial as they improve memory management, code organization, and are fundamental for implementing complex data structures.

Both maps and sets are data structures used in programming, but they serve different purposes and have distinct characteristics:
1. Set:
– Purpose: A set is used to store unique elements.
– Operations: Common operations include adding elements, removing elements, and checking for the existence of elements.
– Uniqueness:Sets automatically handle duplicates, ensuring that each element is unique.
– Implementation:In many languages, sets are often implemented as hash sets, which provide average O(1) time complexity for insertion, deletion, and lookup operations.
– Use Case:Useful for tasks where you need to track a collection of unique items, like ensuring there are no duplicate values in a list.
2. Map (or Dictionary/Hash Table):
– Purpose:A map is used to store key-value pairs.
– Operations: Common operations include inserting a key-value pair, removing a key (and its associated value), and retrieving the value associated with a key.
– Keys: Keys in a map are unique, but values can be duplicated.
– Implementation: Maps are often implemented as hash tables, providing average O(1) time complexity for insertion, deletion, and lookup operations based on keys.
– Use Case:Useful for tasks where you need to associate values with keys, like looking up the meaning of a word in a dictionary.
