Solution: Longest Common Prefix

Explore the use of trie data structures to efficiently find the longest common prefix in an array of strings. Learn how to build and traverse a trie to group common prefixes, reducing redundant comparisons and optimizing search operations 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 strs.length 200\leq 200

  • 00 \leq ...
