Hackerrank Day 7: Arrays | Hackerrank Solutions in C++

Objective
Today, we're learning 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.

Input Format

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

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

4
1 4 3 2

Sample Output

2 3 4 1

Here is the Solution

#include <algorithm>
#include <iostream>

using namespace std;

int main() {
    int N;
    cin >> N;

    int arr[N];

    for (int i = 0; i < N; i++) {
        cin >> arr[i];
    }

    reverse(arr, arr + N);

    for (int i = 0; i < N; i++) {
        cout << arr[i] << " ";
    }

    return 0;
}
