You have been asked to take a small icon that appears on the screen of a smart telephone and scale it up so it looks bigger on a regular computer screen.
The icon will be encoded as characters (x and *) in a 3 x 3 grid as follows:

(refer image1 )

Write a program that accepts a positive integer scaling factor and outputs the scaled icon. A scaling factor of k means that each character is replaced by a k X k grid consisting only of that character.

Input Specification:
The input will be an integer such that 0 < k ≤ 10.

Output Specification:
The output will be 3k lines, which represent each individual line scaled by a factor of k and repeated k times. A line is scaled by a factor of k by replacing each character in the line with k copies of the character.
