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

60             }
61         }
62         cout<<s1<<endl;
63     }
64     return 0;
65  }

总是感觉代码写得复杂了，不过小白就不要求这么多了，AC就好
