How I became a grandmaster on Codeforces
This is one of the hardest problems I've ever managed to solve, and the way that the solution is created is absolutely beautiful and unexpected. It's also the problem that made me red on Codeforces. Do you think you can do it?
Thanks to @AlgorithmsConquered for helping me with the edit at the beginning.
