Hey, I have just started learning some math and basic algorithms and I recently came across this amazing website called CP-algorithms. It had almost everything that I could possibly need but there is one issue. It has just too many topics scattered across their website. Although they do have a navigation page, I don't want to go through all that material. That's why I wanted a more detailed roadmap kind of thing which listed all the topics in order and linked to the CP-algorithms page for the topic. If anyone knows any such thing or has any other recommendation for me please do comment.

I recently started participating in CodeForces contest and am a complete beginner. I currently have a basic knowledge of C++. I can write C++ code for basic problems and programs. Please tell me the rating that I should aim for and how much time it could take on average to reach that rating on CodeForces for clearing ZCO and INOI and getting into the IOITC.

Please answer according to the Indian Informatics Olympiad competition and participation only.
