Solution: Longest Common Prefix

Explore how to apply the trie data structure to efficiently find the longest common prefix in an array of strings. This lesson guides you through building a trie, inserting words, and traversing the structure to identify shared prefixes without redundant comparisons. Understand the time and space complexities involved to optimize your solutions for coding interviews.

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 ...
