{
int n;
int a[];
BufferedReader br;
void get()throws Exception
{
	System.out.println("Enter n");
	 br=new BufferedReader(new InputStreamReader(System.in));
	n=Integer.parseInt(br.readLine());
	a=new int[n];	
}
void pro()throws Exception
{
	for(int i=0;i<n;i++)
	{
		System.out.println("Enter"+(i+1)+"element");
		a[i]=Integer.parseInt(br.readLine());		
	}
}
void show()
{
	for(int i=n-1;i>=0;i--)
		System.out.println(a[i]);
	
}
}
class PrintNReverseMain
{
	public static void main(String arg[])throws Exception
	{
		PrintNReverse obj=new PrintNReverse();
		obj.get();
		obj.pro();
		obj.show();
	}
}
