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:
str1.length,str2.lengthstr1andstr2consist of English uppercase letters. ...
