I wrote two different codes, which differs only on order of headers. Two codes are like these:
include <stdio.h>
include
....(blahblah)....
2.
include
include <stdio.h>
....(blahblah)....
Note: At (blahblah) part, there are 9 millions scanf("%d", &t) operations. Compilation options are both GNU C++14. (GNU C++14 6.2.0, which is used on Codeforces.)
For my opinion, this two code should exactly do the same operations.
But, 1st code gives 1.6ms / 2ms AC, and 2nd code gives TLE. This issue is not about server status, it's still same during many submits.
Can someone help me about what's going on here?
