Problem: Longest Common Prefix

Explore how to identify the longest common prefix shared across multiple strings using a step-by-step horizontal scanning method. Understand the algorithm's logic, time and space complexity, and learn to implement a clean solution in Python for string manipulation problems.

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 ...
