Leetcode is good to learn basic algorithms because problem statements are usually straightforward. Competitive programming has much wider range of problems. Most popular sites for cp are codeforces.com , atcoder.jp, codechef.com . Source: 5 months ago
The de facto standard community for competitive programmers, regular contests with editorials, huge archive of problems (https://codeforces.com/problemset) with pretty accurate difficulty ratings so you can focus on problems of suitable difficulty if you want to progress quickly. They also have an incipient EDU section: https://codeforces.com/edu/courses that covers basic algorithms with practice problems. - Source: Hacker News / 7 months ago
- I used C++ to solve 500+ problems on codeforces.com (a competitive programming website) But I'm rusty now. Source: 9 months ago
Join the codeforces.com cult try out some most solved problems and then there are many other things like cses problemset, a2oj ladders... Just a tip learn c++ stl too (not necessarily now but do it soon). Source: 11 months ago
