Problem: Longest Common Prefix

Explore methods to find the longest common prefix in an array of strings using horizontal scanning techniques. Learn how to iteratively compare and reduce prefixes to identify the shared initial substring while analyzing the algorithm's time and space complexity within given constraints. This lesson helps you implement a practical string algorithm to solve prefix problems efficiently.

Statement

Given an array of strings strs, find the longest common prefix shared among all the strings in the array.

If no common prefix exists, return an empty string "".

Constraints:

  • 11 \leq strs.length 200\leq 200

  • 00 \leq strs[i].length 200\leq 200 ...
