inputstandard input
outputstandard output
You are given two positive integers a and b. In one move you can increase a by 1 (replace a with a+1). Your task is to find the minimum number of moves you need to do in order to make a divisible by b. It is possible, that you have to make 0 moves, as a is already divisible by b. You have to answer t independent test cases.

Input
The first line of the input contains one integer t (1≤t≤1e4) — the number of test cases. Then t test cases follow.

The only line of the test case contains two integers a and b (1≤a,b≤1e9).

Output
For each test case print the answer — the minimum number of moves you need to do in order to make a divisible by b.

Example
input
5
10 4
13 9
100 13
123 456
92 46
output

题意：输入两个数a和b，问a需要加多少才能变成b的倍数

AC代码

#include <cstdio>using namespace std;int main()
{int t;scanf("%d", &t);while (t -- ){int a, b;scanf("%d%d", &a, &b);int t = a % b;if (!t) puts("0");else printf("%d\n", b - t);}return 0;
}

总结

水题，不解释
