Same code gets diffrent verdict between C++17 and C++20

Правка en1, от DisconnectedGraph, 2024-07-29 12:10:17

When I'm solving 1303G, I submitted with C++17 and C++20(same code).

In C++17, the code passes test 2 easily (109ms).

However, the code gets TLE in C++20 (time limit is 6s).

I'm confused, is there an undefined behavior in my code or is the C++20 compiler bugged? Please help.
