Solution: Longest Common Prefix

Explore how to use trie data structures to find the longest common prefix in an array of strings. This lesson teaches you to insert strings into a trie and traverse it to efficiently identify shared prefixes, reducing time complexity compared to character-by-character comparisons.

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 ...
