What happened with __int128_t?

Revision en4, by 0x0002, 2024-06-09 17:32:32

I was solving problem F of ABC just now. And I got passed with long long, but when I change the type into __int128_t, it got wrong answer in most of the cases. Why is that?

Passed with long long.

Wrong answer with int128.

Upd: It is said that __int128_t can not be the index of array. It may cause wrong answer. So it is always not a good idea to use things like #define int __int128_t.
