原理辗转相除法. public int gcd(int i, int j) { if (i == 0 || j == 0) { return 0; } int a = 0, b = 0; if (i >= j) { a = i; b = j; } else { a = j; b = i; } int c = a % b; while(c != 0) { a = b; b = c; c = a % b; } return b; }…
C 语言实例 - 求两数的最大公约数 用户输入两个数,求这两个数的最大公约数. 实例 - 使用 for 和 if #include <stdio.h> int main() { int n1, n2, i, gcd; printf("输入两个正整数,以空格分隔: "); scanf("%d %d", &n1, &n2); ; i <= n1 && i <= n2; ++i) { // 判断 i 是否为最大公约数…
Calculate the sum of two integers a and b, but you are not allowed to use the operator + and -. Example: Given a = 1 and b = 2, return 3. Credits:Special thanks to @fujiaozhu for adding this problem and creating all test cases. 这道题是CareerCup上的一道原题,难道…
