Help me with this one!!! Whatever the logic I'm applying, time limit gets exceeded in the Test Case 4. This is my solution — https://codeforces.com/contest/1328/submission/167650940 I've tried without storing the values and directly printing it but the result was same — Time Limit Exceeded.
It's pretty easy: we have an integer a and we want to find out which another minimal integer we must add to a such that (a + x) % b == 0. let's look at a % b — if it equals to 0, we must add nothing, so just output 0. Else, we just add (b — a % b) and we're done.
