the second guy has a worse rank and more initial rating still he has more delta why

Do you guys use a debugger provided by an ide or debug using print statements only

I am currently in my 2nd year of college I have been practicing on codeforces for a while now and I want to know what is the best time to start using leetcode for Interview preparation.

I know that you can download test case and run it against your code automatically I have downloaded VScode so what should i download to make it work with vs code

Should i learn vim for competitve coding.Any of you guys use it or have any suggestion regarding it

I recently installed VS code for competitive coding But could not find any good tutorials for setting up VSCode.I was hoping You guys could help me setting up VS Code for compettive coding like What extensions to download and so on.Thanks

Codeforces should add a comment section below each problem like spoj . So that before solving it for pracitce we can check if the problem is worth practicising.

WE should have a feature to like or dislike a problem like spoj so that while practising people can choose questions which will help them get better faster
