A mini coding practice platform where users can solve programming problems, submit code, and track their progress — inspired by LeetCode, focused on the core experience:
Choose Problem → Read Question → Write Code → Run → Submit → See Result
Goal: build something that feels like a real product without recreating LeetCode from scratch.
