Problem Description
Everyone hates ugly problems.

You are given a positive integer. You must represent that number by sum of palindromic numbers.

A palindromic number is a positive integer such that if you write out that integer as a string in decimal without leading zeros, the string is an palindrome. For example, 1 is a palindromic number and 10 is not.
 

 

Input
In the first line of input, there is an integer T denoting the number of test cases.

For each test case, there is only one line describing the given integer s (1\leq s \leq 10^{1000}).
 

 

Output
For each test case, output “Case #x:” on the first line where x is the number of that test case starting from 1. Then output the number of palindromic numbers you used, n, on one line. n must be no more than 50. en output n lines, each containing one of your palindromic numbers. Their sum must be exactly s.
 

 

Sample Input
2
18
1000000000000
 
 
Sample Output
Case #1:
2
9
9
Case #2:
2
999999999999
1
 
Hint
9 + 9 = 18 999999999999 + 1 = 1000000000000
