用C语言实现,输入一个18*4的二维数组,对整行进行全排列,并计算每个数 ...答:include <stdio.h>#define NUM_COLUMN 4#define NUM_ROW 18#define NUM_TOTAL NUM_ROW+1int _nums[19][4]={{1,2,3,4},{1,2,3,4},{1,2,3,4},{1,2,3,4},{1,2,3,4},{1,2,3,4},{1,2,3,4},{1,2,3,4},{1,2,3,4},{1,2,3,4},{1,2,3,4},{1,2...
C语言编程:请用1,2,5,7,8,9这六个数字(每个数字至多用一次)来组成一个...答:不算不知道,一算吓一跳,竟然有这么多能被75整除的数。借助全排列函数,末尾是5,其余四位b[4]在a[5]中取,然后判断。include "stdafx.h"include <iostream> include <algorithm> using namespace std;int main(){ int a[5] = { 1,2,7,8,9 },b[4];while (next_permutation(a, a ...
