In problem 1163F, I used a cumbersome code implementation to solve this problem.
And I met some mysterious problem about efficiency of the code,here is the problem.
I got TLE when I submit this code.
At first I think is there anywhere I forgot to use long long(because it may cause some while conditions error). So I use
#define int long long at the front of the code.
Then it got accepted? After that I checked every variables and arrays is sure to be in int.
So I remove #define int long long and resubmitted it in language c++17 (32bits) and got accepted.
#define int long long can cause a 2.5x efficiency difference? I'm very confused about it.
There may be some English grammar errors but they may not affect the reading. Please point them out.qwq
