Actually its not necessary to use fast input output…

I got AC without fast i/o…
There is always an alternative, just think!
Have fun!!!

There is no problem in using faster io to get ac , because if your algo is wrong it would still give tle if you use faster IO . Cin , cout are generally more slow , so even if you have used scanf and printf you could have got ac , without using faster IO .
Check Your solution using scanf and printf gives AC .

you have used scanf and printf . It would be very difficult to do this question using cin and cout .

If the reference to fast i/o is scanf and printf then I am sorry…
It is always recommended by admins (and good coders of codechef, codeforces etc) to always prefer scanf/printf over cin/cout…

If you find my answer useful please upvote and accept it as correct answer .
I am not saying scanf and printf to be fast i/o . I am saying cin/cout will give tle while scanf and print won`t .
