This guy Doflaming0 is a genius. In Educational Codeforces Round 190, he uses Python for problems A, B, and C, then mysteriously switches to C++ for D and E before returning to Python for F. In the solutions for A, B, and C, he even writes Vietnamese comments (perhaps to better organize his thoughts), but for D, E, and F — the harder problems — there are no comments at all.

His unusual coding habits might just be what it takes to become an LGM. Good luck, Doflaming0.
