Arrays Introduction – HackerRank Solution

Arrays Introduction – HackerRank 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.

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.

Sample Input :

4
1 4 3 2

Sample Output :

2 3 4 1

Solution :

#include <cmath>
#include <cstdio>
#include <vector>
#include <iostream>
#include <algorithm>
using namespace std;


int main() {
    int n;
    cin >> n;
    int arr[n];
    for (int i = 0; i < n; i++) {
        cin >> arr[i];
    }
    for (int i = n-1; i >= 0; i--) {
        cout << arr[i] << ' ';
    }  
    return 0;
}
