Problem Statement for "MountainP"

Problem Statement

To make a Mountain Palindrome from a given String you must sort the String's characters in ascending order and then append the fewest number of characters required for it to be a palindrome. A palindrome is a string that is the same backwards as forwards. For example, "ABCCBA", "DEED", and "RADAR" are all palindromes.

Create a class MountainP that contains the method makeMP, which takes a String before and returns a String that is the generated Mountain Palindrome.
