Data Structure & Algorithms
👨💻 Websites & Platforms
HACKERRANK has to be the first platform you should start coding. It has problems in every language you can think of with well-categorized sections.
GEEKSFORGEEKS One site which has helped me improve my problem-solving skills a lot and still helping is GeeksForGeeks, or as often techies call it GFG, is the best portal for Computer Science.
CODECHEF The popularity of Codechef is growing every day amongst the coders of every age group.
CODEFORCES This is one of the portals where the audience base is enormous in terms of numbers and skills. It's one of the most competitive portals for problem-solving.
LEETCODE One of the websites which are industry-recognized. You will see many software developers from Google, Amazon, and Facebook recommend you solve problems on LeetCode.
