Run results for: Square Every Digit (most popular solution on code wars)

Welcome. In this kata, you are asked to square every digit of a number and concatenate them. For example, if we run 9119 through the function, 811181 will come out, because 92 is 81 and 12 is 1. Note: The function accepts an integer and returns an integer
