// Combination formula using non recursion
#include <iostream>
using namespace std;

int fact(int n){
    int product=1;
    while(n>0){
        product *= n;
        n--;
    }
    return product;
}

int C(int n, int r){
    return fact(n)/( fact(r) * fact(n-r));//using formula
}

int main() {
    int n,r;
    cout << "Enter n: " << endl;
    cin >> n;
    cout << "Enter r: " <<endl;
    cin >> r;
    
    cout << "Possible combination would be = " << C(n,r) << endl;
    cout << fact(n);
    return 0;
}
