Dive into LeetCode 2131: Longest Palindrome by Concatenating Two Letter Words! This video breaks down how to construct the longest possible palindrome from a given list of two-letter words. We explore an efficient strategy using frequency counting. Learn how to pair up words like 'lc' with 'cl', and how to utilize palindromic words like 'gg' both as pairs and as a potential central element. The solution involves iterating through word counts, carefully adding lengths from matched pairs (like 'lc...cl') and palindromic words (like 'gg...gg'), and considering a single central word (an unpaired 'aa' type word) to maximize the palindrome's length. We also cover the O(N) time and O(1) space complexity of this clever approach.
Perfect for coding interview preparation and improving problem-solving skills.
