Problem: Longest Common Prefix

Explore how to solve the problem of finding the longest common prefix among an array of strings by implementing a horizontal scanning approach. Understand how to iteratively trim the prefix to match all strings efficiently. This lesson helps you apply string matching techniques, analyze time and space complexity, and code a practical Java solution.

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 ...
