AkshatAggarwal14/Competitive-Programming ? reverse-engineered prompt

Build me a clean competitive programming C++ workspace where I can keep solutions for different sites in separate folders, like AtCoder, CodeChef, Codeforces, CSES, HackerEarth, LeetCode, USACO, and a few practice and learning sections.

I want it to be easy to drop in new solutions, compile them quickly, and reuse common code for things like fast I O, debug helpers, and standard algorithms. Please include a simple Makefile or similar so I can build and run files without much hassle, and make the folder structure feel organized enough for long term use.

It should be set up like a personal CP repository, not a full app, with a focus on being practical and easy to navigate. If anything about the best setup is unclear, use sensible defaults and keep it lightweight. You can look up current C++ and competitive programming conventions online if needed.
