You placed first in a coding contest, feeling like a god among mortals. But then someone else placed 0th because they exploited an integer underflow bug in the ranking system. Classic competitive programming energy right here—where winning isn't about being the best, it's about finding that one edge case the organizers forgot to validate. For the uninitiated: integer underflow happens when you subtract from the minimum value of an integer type and it wraps around to the maximum value (or in this case, goes negative and becomes 0th place). It's like going so far backward you end up ahead. Honestly, if you can hack the leaderboard, you deserve that trophy more than anyone who actually solved the problems.
