Pyramid

This program takes a number input from a file, and makes upside down pyramid of the number, some of the constraints are that numbers higher than 9 must use "*" until they reach the number 9, only accept numbers greater than 0, and you must format the pyramid with spaces. This was a timed challenge so efficiency wasn't taken into account. See results below
