You can always use scanf and printf by including cstdio or stdio.h but sometimes (rarely) you need even faster i/o methods to pass the test cases. That’s when that sync function comes to rescue.

[ 1] This allows std::cout to manage its own buffering independently of what C stdio functions would use, resulting in more efficient operation. This is a global action. Webios_base::sync_with_stdio(0) will de-synchronize cin from scanf and cout from printf.This is fine and will result in a speedup if you just use cin and cout, but if you mix that with stdio-style IO, then weird things happen.For example if the input is 5 6 and your code says. int a, b; scanf("%d", &a); cin >> b; data center technician requirements
