The Trie data structure is a tree-like structure used for storing a dynamic set of strings.

It allows for efficient retrieval and storage of keys, making it highly effective in handling large datasets.

Trie supports operations such as insertion, search, deletion of keys, and prefix searches.

3043. Find the Length of the Longest Common Prefix

You are given two arrays with positive integers arr1 and arr2.

A prefix of a positive integer is an integer formed by one or more of its digits, starting from its leftmost digit. For example, 123 is a prefix of the integer 12345, while 234 is not.

A common prefix of two integers a and b is an integer c, such that c is a prefix of both a and b. For example, 5655359 and 56554 have common prefixes 565 and 5655 while 1223 and 43456 do not have a common prefix.
