Algorithm
Problem Name:
In this HackerRank Functions in C++ programming problem solution,
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.
For arrays of a known size, 10 in this case, use the following declaration:
int arr[10]; //Declares an array named arr of size 10, i.e, you can
store 10 integers.
Note Unlike C, C++ allows dynamic allocation of arrays at runtime without special calls like malloc(). If n = 10, int arr[n] will create an array with space for 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] and so on through arr[9].
You will 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 space-separated integers.
Constraints
- 1 <= N <= 1000
- 1 <= A[i] <= 10000, where A[i] is the i**th integer in the array.
Output Format
Print the N integers of the array in the reverse order, space-separated on a single line.
Sample Input

1 4 3 2
Sample Output
2 3 4 1
