Description
Domo is a brilliant dog hacker, he wants to find out the password of your computer.
This time, he successfully obtained the compressed file containing the password, all he needed to do was unzip it.
The correct format of a password zip must be [integer][alpha][integer][alpha][integer][alpha]......
where [integer] is an integer greater than 0, representing the number of repetitions for the following alphabet.
[alpha] is a letter from the set of [a-z], [A-Z], or ['0', '1', ..., '9']
[integer][alpha] is a basic zip pair unit.
Here are some examples:
| Before Unzip | After Unzip |
| 3a3d4'1' | aaaddd1111 |
| 2'5'3'7'2c | 55777cc |
| 5ad3c | Can't Unzip (Wrong format) |
| 5d3s3 | Can't Unzip (Wrong format) |
| 5d3s0g | Can't Unzip (integer must > 0) |
Given the zipped string, please help Domo find the correct unzip string (which is the password of the computer). If the string can't be unzipped, output "Domo cannot crack this computer"
Input
The input consists of multiple zipped strings (1 ≤ number of strings ≤ 100), separated by a newline character.
In each string (1 ≤ the length of string ≤ 1000), the [integer] is guaranteed to consist of a number N (0 ≤ N ≤ 100) without any leading zero. There are only uppercase and lowercase letters, digits, and single quotes in the string.
Notice that 0 can appear in the string, but the string can't be unzipped.
Output
Output the corresponding password for every string. It's guaranteed that the length of every unzipped string is less than 1000000.
Remember to print a newline character at the end of every password.
