When to use fast input output

Правка en1, от taap_cader, 2021-04-26 08:57:00

Sometimes when I do question of around 10^7 operations, I don't need to use fast io but the questions which can be solved with 10^5 operations gets TLE without using fast io. Is there some trick to guess when do we need to use fast io or it we have to use it in every question.
