Solution: Greatest Common Divisor of Strings
Understand how to identify the largest common divisor string that can form two given strings by repeating a base pattern. Explore the use of string concatenation checks and the Euclidean algorithm to compute the greatest common divisor of their lengths, enabling you to solve this string problem effectively.

Statement
For two strings s and t, we say that t divides s if and only if s can be formed by concatenating one or more copies of t together (i.e., s = t + t + ... + t).
Given two strings str1 and str2, return the largest string x such that x divides both str1 and str2. If no such string exists, return an empty string.
Constraints:
