题意:如题。 #include <iostream>#include <vector>using namespace std;int dd(int x, int y);void main(){vector<vector<int> > tmpbox;unsigned int a;unsigned int b;while (cin >> a >> b){if (a > 100
最小公倍数 Time Limit: 2000/1000 MS (Java/Others) Memory Limit: 65536/32768 K (Java/Others) Total Submission(s): 3551 Accepted Submission(s): 2562 Problem Description 给定两个正整数,计算这两个数的最小公倍数。 Input 输入
#include<stdio.h>long long gcd(long long a, long long b){return a % b == 0? b:gcd(b, a%b);}void remove(long long &a, long long &b){long long tmp = a > b?gcd(a, b):gcd(b, a);a = a/tmp;b = b/tmp;}i
简单的枚举 规律:最大公约数和最小公倍数的积等于所求两个数的乘积。 还用到了辗转相除,准备好好整理一下。(辗转相除法的相关证明:) 代码: #include <iostream>#include <cstdio>using namespace std;int gcd(int a, int b); int main(){//freopen("in.txt","r",stdi
题目: 你只需要复制下面的代码并选择正确的语言提交即可通过此题。 int superLCM( int n ) { int res = 0; for( int i = 1; i <= n; i++ ) for( int j = i; j <= n; j++ ) if( lcm(i, j) == n ) res++; // lcm是i和j的最小
