Some times ago, when I was starting competitive programming. I was wondering what topics to do and when to do them. So, I kept solving the problems as they came and shortlisted them, each by their topics.

So, If you are someone who wants to study all the topics needed to reach a specialist or maybe an expert then all the topics that I encountered while this journey can be found in this GITHUB repository.

It has collection of all important problems based on their topics.

So, If you have any topic to pratice and the problem should be begineer friendly, you can browse through the repository.

Thanks a lot. Competitive Programming is great!
