Description

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. (81-1-1-81)

Example #2: An input of 765 will/should return 493625 because 7² is 49, 6² is 36, and 5² is 25. (49-36-25)

Note: The function accepts an integer and returns an integer.

Happy Coding!
