#include <bits/stdc++.h>
using namespace std;

int main(){
    int n;
    cout << "No.of elements \n";
    cin >> n;
    int a[n];
    cout << "Enter the elements \n";
    for (int i = 0;i<n;i++)
        cin >> a[i];
    int temp = a[0];
    a[0] *= a[1];
    for(int i=1;i<n-1;i++){
        int t = a[i];
        a[i] = temp*a[i+1];
        temp = t;
    }
    a[n-1] *= temp;
    for(int i=0;i<n;i++)
        cout << a[i] << "  ";
}
