Hello Codeforces,
Just got TLE on 2116C - Gellyfish and Flaming Peony using __gcd, but after switching to gcd from <numeric>, my code got AC!

TLE Submission (using __gcd): Submission #322284306
AC Submission (using std::gcd): Submission #322321593

I couldn't find a clear reason online for this difference.
If anyone knows why this happens, please share in the comments section!
