You are given a string 'S'. Your task is to check whether the string is palindrome or not. For checking palindrome, consider alphabets and numbers only and ignore the symbols and whitespaces.

Note :

String 'S' is NOT case sensitive.

Example :

Let S = “c1 O$d@eeD o1c”.
If we ignore the special characters, whitespaces and convert all uppercase letters to lowercase, we get S = “c1odeedo1c”, which is a palindrome. Hence, the given string is also a palindrome.

Passwords should be easy to remember but difficult to hack or guess. According to Ninja Cyber Security Centre, a password should have a minimum of 6 lengths and a maximum of 20 lengths. It should have at least one lowercase letter, one uppercase letter, and one digit. The most important condition is that the password should not contain any repeating characters of length more than 2.

Given a string ‘STR’ as a password, find the minimum number of changes we need to make to strengthen that password. We can insert a character, delete a character and replace a character from the password at a time.
