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 100.

  Output

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

  Sample Input

2
  ABC
  ABBCCC

  Sample Output

ABC
  A2B3C
