Solution: Longest Palindrome

Solution: Longest Palindrome

Let’s solve the Longest Palindrome problem using the Hash Map pattern.

We'll cover the following...

Statement

Given a string s that contains only letters, return the length of the longest palindrome that may be composed using those letters.

Note: Letters are case-sensitive. For example, “Aa” is not considered a palindrome here.

Constraints:

  • 1≤1 \leq s.length ≤2000\leq 2000 ...
