Bobo has an n×m picture consists of black and white pixels. He loves the picture so he would like to scale it a×b times. That is, to replace each pixel with a×b  block of pixels with the same color (see the example for clarity).

Input

The input contains zero or more test cases and is terminated by end-of-file. For each test case,

The first line contains four integers n,m,a,b . The i-th of the following n lines contains a binary string of length m which denotes the i-th row of the original picture. Character "0" stands for a white pixel while the character "1" stands for black one.

• 1≤n,m,a,b≤10
• The number of tests cases does not exceed 10.

Output

For each case, output n×a rows and m×b columns which denote the result.
