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.
 
Sample Input
