直接开把代码

#include <iostream>
using namespace std;
int n;
int main(){
    cin>>n; 
    if(n == 0){
        cout<<"0 0 0"<<endl;
        return 0;
    }   
    for(int p=n/14;p>=0;p--){
            for(int j=p;j<=n/4;j++){
                for(int k=p;k<=n/3;k++){
                    if(p*7+j*4+k*3 == n){
                        cout<<p<<" "<<j<<" "<<k<<endl;
                        return 0;
                    }
                }
            }
    }   
    cout<<"-1"<<endl;
    return 0;
}
