DONT USE STD::ENDL!
By Meron3r, history, 8 months ago, In English

Why??? You might be asking... well, std::endl is the most common thing that might be giving you TLE. It's because std::endl flushes every time. But on the other hand, '\n' only flushes once every 1000 times because is is just a newline character. But if you are used to writing std::endl or endl, you can just make a define for it. #define endl "\n". If you think I am wrong, just comment, don't dislike.

It’s rarely to encounter a TLE like that on Codeforces problems. 1207F - Remainder Problem is one such example when the endl really slows things down. But endl has its uses, such as in interactive problems.

You're right, but you shouldn't do Define!
