Solution: Longest Common Prefix

Explore how to implement a Trie to find the longest common prefix among multiple strings efficiently. This lesson guides you through inserting words into a Trie and traversing it to identify shared prefixes, improving your ability to solve similar string manipulation problems in coding interviews.

We'll cover the following...

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:

  • 1≤1 \leq strs.length ≤200\leq 200

  • 0≤0 \leq ...
