Problem
- Palindrome Permutation
- Given a string, write a function to check if it is
- permutation of a palindrom.
- A palindrome is a word or phases that is the same forwards and backwards.
- A permutation is a rearrangement of letters.
- The palindrome does not need to be limited to just dictionary word
Code
