Many optimizations and tricks were applied by others. It requires a lot of skill to implement everything on a high level.

Writing the fastest possible program *for a specific dataset* is not the same thing as writing the fastest program for an arbitrary dataset of that size. And, indeed, the fastest program is the one that does nothing but print the answer. Speed on this task doesn't tell you anything about performance with different types/sizes of data or constraints on programmer time needed to produce a correct implementation and maintain it over time.
