import java.util.*;
class Main {
public static void main(String args[]) {
Scanner scan=new Scanner(System.in);
int n=scan.nextInt();
int arr[]=new int[n];
for(int i=0;i<arr.length;i++){
arr[i]=scan.nextInt();
}
Stack s=new Stack<>();
for(int i=0;i<arr.length;i++){
while(!s.isEmpty()&& arr[i]>s.peek()){
int rv=s.pop();
System.out.print(arr[i]+" ");
}
s.push(arr[i]);

    }
    if(!s.isEmpty()){
        System.out.print(-1);
        s.pop();
    }
