git commit -m "Solve: Two Sum"

Every problem you solve becomes a real commit in your own repo.

GreenGrid organizes the coding problems you solve — with notes, complexity, and code — and pushes each solution straight to your own GitHub repository. No fake contribution graphs. Every green square is work you actually did.
