@x1007 要写一个判断函数

by Dark_Monarch @ 2024-02-01 15:12:32

@x1007

#include<bits/stdc++.h>

using namespace std;

int A,B,C;

int cnt[10];
bool check(int x){
    if(A == 0) return false; 
    if(x * B % A != 0)
        return false;
    int y = x * B / A;
    if(C * y % B != 0)
       return false;
    int z = C * y / B;/*判断x:y:z 是否等于A:B:C*/

    if(y < 100 || y > 999) return false;
    if(z < 100 || z > 999) return false;

    memset(cnt,0,sizeof(cnt));/*清空*/

    int x_ = x, y_ = y, z_ = z;/*备份*/
    for(int i = 1;i <= 3;i++){
        cnt[x % 10] ++; x /= 10;
        cnt[y % 10] ++; y /= 10;
        cnt[z % 10] ++; z /= 10;
    }

    for(int i = 1;i < 10;i++)
        if(cnt[i] != 1)
            return false;

    cout << x_ << ' ' << y_ << ' ' << z_ << endl;
    return true;
}

int main(){
    cin >> A >> B >> C;
    int o = 0;
    for(int x = 123;x <= 987;x++){
        if(check(x))
            o++;
    }

    if(o == 0){
        cout << "No!!!";
    }

    return 0;
}
