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 cause some undefined behaviors or something like that.
Thanks for reading!
