Length Of Longest Palindrome

Given a string, find the length of the largest palindrome that can be made from the characters in the string. A palindrome is a word, phrase, number, or other sequence of characters that reads the same forward and backward, ignoring spaces, punctuation, and capitalization.

Example 1:

Input:

s = 'racecar'

Output:

largest_palindrome(s) -> '7'

In this example, the entire string ‘racecar’ is a palindrome.

Example 2:

Input:

s = 'aabbcc'

Output:

largest_palindrome(s) -> '6'
