和第一种解法思路类似,依旧是借助字符串的特性,使用替换来验证最大公约数,通过String的replaceAll方法实现。 publicStringgcdOfStrings2(String str1, String str2){if(!(str1+str2).equals(str2+str1)) {return""; }intn=Math.min(str1.length(), str2.length());for(inti=n; i>=1; i--) {if(...

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
链接:https://leetcode-cn.com/problems/greatest-common-divisor-of-strings。 02 解题思路 欧几里得算法 这道题需要用到起源于公元前300年的古老算法——欧几里得算法。 定理:两个整数的最大公约数等于其中较小的那个数和两数相除余数的最大公约数。最大公约数(Greatest Common Divisor)缩写为GCD。 gcd(a,b) ...
