I have submitted the same algorithm with different input streams (cin and scanf) , I used ios_base::sync_with_stdio(false);cin.tie(NULL); with the cin and cout but still got a high difference in speeds?

Can somebody explain??

The problem link that I submitted is this one-- https://mirror.codeforces.com/problemset/problem/368/B
