Today,I'm solving abc331_f.I used brute force at that moment.Its time complexity is $$$\Theta(nq)$$$ which $$$n$$$ is not greater than $$$10^6$$$ and $$$q$$$ is not greater than $$$10^5$$$.but I passed it in about $$$1$$$ second.
Soon I found the problem:I used C++23 Clang 16.0.0 to submit it in the beginning and it passed,but when I used C++20 gcc 12.2 to submit it,it got TLE.
So please can somebody tell me the reason?Thanks.
And here's my code.
Today,when I was doing problem on Atcoder,I found an interesting thing.
ABC317 was held on Aug.26 and ABC 315 was held on Aug.19.
So who can tell me where's ABC316,please?
