Longest Palindrome
Understand how to determine the longest palindrome length from a given string with case-sensitive letters. Learn to use hash maps efficiently in C++ to count characters and derive the solution in optimal time and space complexity. This lesson helps you build foundational skills for coding interview problems involving pattern recognition and data structures.

Statement
Given a string s that only contains alphabets, return the length of the longest palindrome that may be composed using those letters.
Note: Letters are case-sensitive. Hence, combinations such as “
Aa” are not considered palindromes.
