Hi everyone! Hope you guys a nice weekend!

Recently, I have tried to submit my solutions in both GNU C++17 and GNU C++17(64). The result is predictable, GNU C++17(64) is faster compared to GNU C++17. My question is: Is it safe to use C++17(64) in the real contest? I know that C++17(64) was just added a few months ago. So I don't know whether it may lead to some undefined behavior bugs or something like that...

Thanks for reading!

Hi everyone! In recent contests, my friends and I did not perform well. However, our ratings still increased somehow. In addition, CF predictor is no longer precise these days. Maybe I'm not the only one who feel strange. Then, did Codeforces change their formula for rating system?
