Time limit exceeded in Enormous Input Test Problem?

I have started solving Beginner problems. In my second problem, I am getting this error. I googled as you suggested, but didn’t get an exact answer.

You need to use Fast I/O for that problem.
Here’s an awesome article summing up the time taken by various I/O and their improvisations.

Thanks for helping guys.

Just for quick help,

Use scanf() of course

And you must process the data right after every time you take an input. Remember, you don’t need an array for this.
