Problem Description

Given a string containing only 'A' - 'Z', we could encode it using the following method:
1. Each sub-string containing k same characters should be encoded to "kX" where "X" is the only character in this sub-string.
2. If the length of the sub-string is 1, '1' should be ignored.

 

Input

The first line contains an integer N (1 <= N <= 100) which indicates the number of test cases. The next N lines contain N strings. Each string consists of only 'A' - 'Z' and the length is less than 10000.

 

Output

For each test case, output the encoded string in a line.

            while(str[i+1] == c)

                count++;
                i++;

            if(count)
            {
                printf("%d%c",count+1,c);
                count = 0;
                c = str[i+1];
            }
            else
            {
                printf("%c",c);
