The only Leet Code problems I am able to solve on my own are the most simplest and straightforward ones on Coding Bat(https://codingbat.com/java). And I haven't even got the chance to solve all of them yet, so I've really only been trying out its first few and am not sure if it gets any harder. Source: 10 months ago
If you’re struggling with Loops and Arrays i’d recommend doing exercises focused just on them. I went through the same thing and I went through the exercises on https://codingbat.com/java and got familiar with both of them. If you get stuck on a problem don’t be afraid to look at the solution and learn about how it works. Source: 11 months ago
I used this video series to get ahead of my intro to cs class. I’d recommend you find something similar to learn from. Just learn the basics, and you’ll be much more prepared for your college class. What’s really important is to do a lot of practice problems, and not just watch videos to learn the concepts. If you learn in Java or python, you can do practice problems in coding bat: https://codingbat.com/java. Source: 12 months ago

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
