How to take fast I/O in C++? I am solving a problem where number of test cases can be 10^6 so i guess fast I/O will help to speed up my solution.

+1 but sometimes it's not enough
Another possible way is to implement your own reader for integer/real/signed types using
getchar()
:In most cases coders use it to get top1 by execution time))
But in case
N = 10^6
it may be useful to beat TL with solution that wasn't intended by jury.Thanks it did reduce my time but still TLE. I guess i have to improve my algo.
