Arrays Introduction in C++ Hacker Rank Solution

Problem

An array is a series of elements of the same type placed in contiguous memory locations that can be individually referenced by adding an index to a unique identifier.
Declaration:

int arr[10]; //Declares an array named arr of size 10, i.e; you can store 10 integers.

Accessing elements of an array:

Indexing in arrays starts from 0.So the first element is stored at arr[0],the second element at arr[1]...arr[9]

You’ll be given an array of N integers and you have to print the integers in the reverse order.


Input Format

The first line of the input contains N,where N is the number of integers.The next line contains N integers separated by a space.

Constraints

  • 1<= N <= 1000
  • 1<= Ai <= 10000 where Ai is the ith integer in the array. 

Output Format

Print the N integers of the array in the reverse order in a single line separated by a space.


Sample Input

4
1 4 3 2

Sample Output

2 3 4 1
