 Problem


Objective
Today, we will learn about the Array data structure. Check out the Tutorial tab for learning materials and an instructional video.

Task
Given an array, , of  integers, print 's elements in reverse order as a single line of space-separated numbers.

Example

Print 4 3 2 1. Each integer is separated by one space.

Input Format

The first line contains an integer,  (the size of our array).
The second line contains  space-separated integers that describe array 's elements.

Constraints

Constraints

  • , where  is the  integer in the array.

Output Format

Print the elements of array  in reverse order as a single line of space-separated numbers.

Sample Input

My Solution C++


#include <bits/stdc++.h>
#include <iostream>
#include <algorithm>
#include <string>

using namespace std;





int main()
{
    
     int n;
    cin >> n;
    
    int A[n];
 
    
    for (int i = 0; i < n; ++i) {
        cin >> A[i];

    }
    
    for (int i = n-1; i >=0; i--){
        cout << A[i] << " ";
    }
    
    return 0;
}
