题目看着一句就行：For example, the string 122344111 can be described as "one 1, two 2's, one 3, two 4's, three 1's". 
#include<cstdio>
char a[1005];
int i, s, k,t;
int main()
{
	scanf("%d", &t);
	while (t--&&scanf("%s", a))
	{
		k = 0, i = 1;
		while (a[++k])
			if (a[k] == a[k - 1]) i++;
			else printf("%d%c", i, a[k - 1]), i = 1;
			printf("%d%c\n", i, a[k - 1]);
	}
}
