Given you N positive integers, your job is to output these N numbers in the ascending order in every digit (if two numbers in some digit are the same, you should output the smaller one first). For example, there are five numbers 1 11 111 1111 11111. You should output five lines as sample output. If a number doesn't have the i^th digit, you can consider its i^th digit zero.

Input

The input contains several test cases. Each case contains two lines. The first line contains a positive integer N (N ≤ 1000), indicating the length of the sequence. The second line gives N numbers (each number will not exceed 2147483647). If N = 0 it signals the end of the input and isn't considered to be processed.

Output

Each case contains several lines. The first line is indicated as sample output. The i + 1 line contains these N numbers in ascending order in the i^th digit.

Sample Input

5
1 11 111 1111 11111
7
19 28 37 46 55 55 45
0

Sample Output

Case 1:
1 11 111 1111 11111
1 11 111 1111 11111
1 11 111 1111 11111
1 11 111 1111 11111
1 11 111 1111 11111
Case 2:
45 55 55 46 37 28 19
19 28 37 45 46 55 55
