Solution: Find the Length of the Longest Common Prefix

Explore how to efficiently compute the longest common prefix length between elements of two integer arrays using hash maps. This lesson guides you through generating numeric prefixes, leveraging hash sets for quick lookups, and optimizing checks to handle large datasets effectively.

Statement

You are given two arrays of positive integers, arr1 and arr2.

A prefix of a positive integer is an integer formed by one or more of its digits, starting from the leftmost digit. For example, 123123 is a prefix of 1234512345, while 234 234 is not.
