而str1 ="LEET",str2 ="CODE",str1拼接str2后变成"LEETCODE",str2拼接str1后变成"CODELEET",两者显然不相等,肯定不存在公约数。 那怎么找到他们的最大公约数呢? 思路:借助字符串拆分。用不同的子串分别对str1和str2进行拆分,通过String的split方法实现,如果拆分后的字符串数组中没剩下任何元素,表明可以被...

Can you solve this real interview question? Greatest Common Divisor of Strings - For two strings s and t, we say "t divides s" if and only if s = t + t + t + ... + t + t (i.e., t is concatenated with itself one or more times). Given two strings str1 and
Can you solve this real interview question? Greatest Common Divisor Traversal - You are given a 0-indexed integer array nums, and you are allowed to traverse between its indices. You can traverse between index i and index j, i != j, if and only if gcd(nu

The space complexity is O(1) constant, and the time complexity is O(M/N) where M is the length of the longer string and N is the shorter length e.g. “A”, and “AAAAAAA…” See also:Teaching Kids Programming – Greatest Common Divisor of Strings ...
1071. Greatest Common Divisor of Strings(字符串的最大公因子) 链接 https://leetcode-cn.com/problems/greatest-common-divisor-of-strings 题目 对于字符串 S 和 T,只有在 S = T + ... + T(T 与自身连接 1 次或多次)时,我们才认定 “T 能除尽 S”。
Return the largest stringXsuch thatXdivides str1 andXdivides 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:"" ...
Given an integer array nums, return the greatest common divisor of the smallest number and largest number in nums. The greatest common divisor of two numbers is the largest positive integer that evenly divides both numbers. Example 1: Input: nums = [2,5,6,9,10] Output: 2 Explanation: The...
