#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 max=a[n-1];
    a[n-1] = -1;
    for (int i = n-2;i>=0;i--){
        int t = a[i];
        a[i]=max;
        if (t>max)
            max=t;
    }
    for (int i=0;i<n;i++)
        cout<<a[i]<<"  ";
}
