I was solving 1610H - Squid Game, and after submitting, I thought that the TLE verdict that I got is mysterious and I didn't know why. But after I changed language to C++17, it comfortably passed in under 500ms. And I changed it again to C++20, the result is similar, hinting that my code might be correct.

The three submissions should be identical except languages. 328699971 328700051 328700454

I'm not a compiler expert and I'm too lazy to construct a smaller breaking code, so I'm just posting an example here.
