I'm a beginner and I have just approached codeforces. I didn't know anything about DSA, Competitive Programming, etc... I want you to help me by giving some tips for solving codeforces problems and competitive programming problems, with a question should I look up editorial when I am stuck on a problem when practising or keep trying to solve them? I appreciate anyone who gives me the answer because I've looked up on the internet and their answers are mostly too general, so I need help from guys. Please help me answer these 2 main questions: 1. Tips for problem-solving (competitive programming) 2. Should I look up on editorial each time I get stuck?
