Solution: Longest Common Prefix

Explore how to implement a trie-based approach to find the longest common prefix in an array of lowercase strings. This lesson guides you through building a trie, inserting words, and traversing it to identify shared prefixes efficiently. Learn time and space complexities involved to understand the solution's performance advantages when handling large string datasets.

Statement

Given an array of strings, strs, write a function to find the longest common prefix string in strs. If there is no common prefix, return an empty string, "".

Constraints:

  • 11 \leq ...
