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.

        l=strlen(b);
        b[l]=‘a‘;b[l+1]=‘\0‘;
        l++;
        int num=1;
        for(i=1;i<l;i++)
        {
            if(b[i]!=b[i-1])
