Write a function string remove Characters (string str, string remove); that returns a new string consisting of the characters in str after removing all instances of the characters in remove. For example, if you call remove Characters ("counterrevolutionaries", "aeiou") the function should return "cntrrvltnrs", which is the original string after removing all of its vowels.
