Define a class Anagram to accept two words from the user and check whether they are anagram of each other or not.
An anagram of a word is another word that contains the same characters, only the order of characters is different.
For example, NOTE and TONE are anagram of each other.Define a class to accept a number and check whether the number is valid number or not. A valid number is a number in which the eventual sum of digits of the number is equal to 1.
e.g., 352 = 3 + 5 + 2 = 10 = 1 + 0 = 1
