Hello, Codeforces.

I've sent different submissions with same code with different compilers on problem Burenka Plays with Fractions from last round and got different results.

• WA 13 with:

  GNU G++20 11.2.0 (64 bit, winlibs) → 168824855

  GNU G++17 9.2.0 (64 bit, msys 2) → 168878170

• ACC with:

  GNU G++17 7.3.0 → 168877257

  GNU G++14 6.4.0 → 168878015

I would've gotten a higher rate if this strange thing hadn't happened.

Strange that I get wrong answer with modern compilers and accepted with old compilers !

Can anyone explain that ?!
