Problem J3: Icon Scaling

Problem DescriptionCopy Anchor Link

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 $3\times 3$ grid as follows:

*x*
 xx
* *

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 $k\times k$ grid consisting only of that character.

Input SpecificationCopy Anchor Link

The input will be a positive integer $k$ such that $k \lt 25$.

Output SpecificationCopy Anchor Link

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.
