Problem
I'm a beginner and I have just approached Codeforces. I didn't know anything about DSA, Competitive Programming, etc...
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:
Tips for problem-solving (competitive programming)
Should I look up on editorial each time I get stuck?
If you don't know anything about DSA or CP, you can go with usaco.guide, it's more than enough resource to learn and practice. And also watch this video, it has almost all the advices you want.
