题目描述

The I-number of x is defined to be an integer y, which satisfied the the conditions below:
1. y>x;
2. the sum of each digit of y(under base 10) is the multiple of 10;
3. among all integers that satisfy the two conditions above, y shouble be the minimum.
Given x, you're required to calculate the I-number of x.

输入

An integer T(T≤100) will exist in the first line of input, indicating the number of test cases.
The following T lines describe all the queries, each with a positive integer x. The length of x will not exceed 10⁵.

输出

Output the I-number of x for each query.

样例输出

题意懂了，就是一个水题，不懂你就过不了，这个题有三个条件

1 y>x
2 每一位的和相加是10的倍数
3 输出最小的y

代码：

# include <stdio.h>

int qwe(int x)  // 每一位的和
{
	int sum = 0;  
	while (x != 0)
	{
		sum += x%10;
		x /= 10;
	}
	return sum;
}

int main(void)
{
	int t;
	scanf("%d", &t);
	while (t --)
	{
		int n, c;
		scanf("%d", &n);
		n ++;
		while (1)
		{
			c = qwe(n);
			if (c % 10 == 0) // 满足结束，输出
			{
				printf("%d\n", n);
				break;
			}
			n ++; // 不满足继续加。
		}
	}
	return 0;
}
