#define _CRT_SECURE_NO_WARNINGS
#include<iostream>
using namespace std;
int main(){
    int n;
    cin>>n;
    int cnt_m,cnt_w;
    bool flag = false;
    for(cnt_m=0;cnt_m<n;cnt_m++){
        for(cnt_w=0;cnt_w<n;cnt_w++){
            if(5*cnt_m+3*cnt_w==n){
                cout<<"men = "<<cnt_m<<", women = "<<cnt_w<<", child = "<<n-cnt_w-cnt_m<<endl;
                flag=true;
            }
        }
    }
    if(!flag)cout<<"None";
    return 0;
}

men = 0, women = 15, child = 30
men = 3, women = 10, child = 32
men = 6, women = 5, child = 34
men = 9, women = 0, child = 36
