Write a method that accepts a positive integer parameter and returns that value as an integer, but "sorted" to have its digits in increasing order. For example, sortNum(72081) would return 1278 since the increasing order of the digits would be 0, 1, 2, 7, and 8, but the zero is not significant when placed as the first digit. There are several interesting ways of solving this problem, so you might want to look for alternative solutions after you solve it one way.
