Palindrome Pairs

Explore how to find all palindrome pairs within an array of unique strings by concatenating pairs to form palindromes. Learn to implement trie data structures for efficient string searches. This lesson helps you understand and solve palindrome pair problems with optimal time complexity in coding interviews.

Statement

You are given a 0-indexed array of unique strings called words.

A palindrome pair is defined as a pair of indexes (i, j) where both i and j are within the valid range of the list of words (that is, 00 \leq i, j << ...
