杭电1020-Encoding

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

2

ABC

ABBCCC

 

Sample Output

ABC

A2B3C
