@LXLS 选择代码语言啊

#include<iostream>
using namespace std;
int a[5],b[5],c[5];
int q,w,e,ppt = 1;
int main()
{
    cin >> q >> w >> e;
    for(int i = 123;i <= 999; i++)
    {
        a[1] = i / 100;
        a[2] = i / 10 % 10;
        a[3] = i % 100 % 10;
        b[1] = i / q * w / 100;
        b[2] = i / q * w / 10 % 10;
        b[3] = i / q * w % 100 % 10;
        c[1] = i / q * e / 100;
        c[2] = i / q * e / 10 % 10;
        c[3] = i / q * e % 100 % 10;
        if(a[1] + a[2] + a[3] + b[1] + b[2] + b[3] + c[1] + c[2] + c[3] == 45 && a[1] * a[2] * a[3] * b[1] * b[2] * b[3] * c[1] * c[2] * c[3] == 362880)
        {
            ppt = 0;
            cout << i << " " << i / q * w << " " << i / q * e << endl;

@童年如作业 什么什么QAQ...

by LXLS @ 2019-03-01 23:05:07

no写成NO了..... 但也还是得了80，最后一个点WA了 求大佬帮助QAQ

by 童年如作业 @ 2019-03-01 23:06:04

实际上你思路有问题……

你只用把 A:B:C 的ABC三个数不断翻倍就行了。例如样例，从一倍（1,2,3）开始，不断地把倍数+1，二倍（2,4,6），三倍（4,5,6）……（选择性忽略无意义枚举）……一百倍（100,200,300），一百九十二倍（192，384,576），二百一十九倍（219,438,657），以此类推，再在这些数中寻找符合题目条件的即可

@童年如作业 感谢大佬，我去琢磨琢磨 QAQ

@LXLS 这是我的核心代码（由于我码的输入输出对你不友好我删了）

for(register int i=1;c*i<=999;i++)
    {
        if(a*i<100) continue;
        bool t=true;
        int ta=a*i,tb=b*i,tc=c*i;
        memset(pd,0,sizeof(pd));
        while(ta>0)
        {
            if(pd[ta%10]==1||ta%10==0)
            {
                t=false;
                break;
            }
            pd[ta%10]=1;
            ta/=10;
        }
        while(tb>0&&t)
        {
            if(pd[tb%10]==1||tb%10==0)
            {
                t=false;
                break;
            }
            pd[tb%10]=1;
            tb/=10;
        }
        while(tc>0&&t)
        {
            if(pd[tc%10]==1||tc%10==0)
            {
                t=false;
                break;
            }
            pd[tc%10]=1;
            tc/=10;
        }
}
