Solution: https://github.com/therajatg/DSA/blob/main/009-valid-palindrome.js
Given a string s, return true if it is a palindrome, otherwise return false.
A palindrome is a string that reads the same forward and backward. It is also case-insensitive and ignores all non-alphanumeric characters.
Note: Alphanumeric characters consist of letters (A-Z, a-z) and numbers (0-9).
Example 1
racecar
madam
level
12321
Example 2:
"Was it a car or a cat I saw?"
