Define and write a boolean function isAnagram(s1,52) that checks whether two words (s1 and s2) are anagrams. If they are anagrams, the function should return a True, otherwise a False. Two words are anagrams if they contain the same letters in any order. For example, silent and listen are anagrams. Write a python program that prompts the user to input two strings, then outputs whether the strings are anagrams or not. Use a main function in your solution. Only use of the len(),input(), and print() built-in functions are permitted.
