The key to getting better at programming is consistent practice. Try solving problems on websites like LeetCode, HackerRank, and CodeSignal. Start with easy problems and gradually move up in difficulty. Source: 11 months ago
For CS, you'll have a headstart if you have a bit of experience with Python and problem-solving. Search around for basic material on Python and if you have the time, attempt some problems on https://dmoj.ca/. Source: 10 months ago
Dmoj.ca ! It's meant more so for competitive coding but some of the problem sets they have fall under the Cryptography category. Source: 12 months ago
The first type of practice is general problem solving. This is where you build up a strong intuition of problem and develop general problem solving techniques (but not memorising a huge list of techniques). Of course, the only way to improve is to do lots of problems / contests. For those who are more interested in competitive programming, I really like dmoj.ca (they host contests there as well, sometimes I author... Source: over 1 year ago
Personally, I’ve heard good stuff about DMOJ https://dmoj.ca/ Hope it helps :). Source: over 1 year ago
Sign up for an account on dmoj.ca or similiar online judge website and do the problems there. They have ccc problems and waaay more that you can get your solutions judged instantly. Source: almost 2 years ago
