1071 - Greatest Common Divisor of Strings\. Easy For two strings `s` and `t`, we say "`t` divides `s`" if and only if `s = t + ... + t` (i.e., `t` is concatenated with itself one or more times). Given two strings `str1` and `str2`, return _the largest string_ `x` _such that_ `x` _divides both_ `str1` _and_ `str2`. **Example 1:** **Input:** str1 = "ABCABC", str2 = "ABC" **Output:** "ABC" **Example 2:** **Input:** str1 = "ABABAB", str2 = "ABAB" **Output:** "AB" **Example 3:** **Input:** str1 = "LEET", str2 = "CODE" **Output:** "" **Constraints:** * `1 <= str1.length, str2.length <= 1000` * `str1` and `str2` consist of English uppercase letters.
