In this article, we will be solving **HackerRank Day 7: Arrays** problem, part of **30 Days of Code**. Majorly, we will use ** Python3** and

**to solve the problem.**

*Java15*#### 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, ** A**, of

**integers, print**

*N***‘s elements in reverse order as a single line of space-separated numbers.**

*A*#### Example

*A = [1,2,3,4]*

Print `4 3 2 1`

. Each integer is separated by one space.

#### Input Format

The first line contains an integer, ** N** (the size of our array).

The second line contains ** N** space-separated integers that describe array

**‘s elements.**

*A*#### Constraints

- 1 <=
*N*<= 1000 - 2 <= A[i] <= 10000, where A[i] is the i
^{th}integer in the array.

#### Output Format

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

#### Sample Input

```
4
1 4 3 2
```

#### Sample Output

`2 3 4 1`

### Solution Day 7: Arrays in Python3

```
#!/bin/python3
import math
import os
import random
import re
import sys
if __name__ == '__main__':
n = int(input().strip())
arr = list(map(int, input().rstrip().split()))
print (*arr[::-1])
```

### Solution Day 7: Arrays in Java15

```
import java.io.*;
import java.util.*;
public class Solution
{
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
int n = in.nextInt();
int[] arr = new int[n];
for(int i=0; i < n; i++) {
arr[i] = in.nextInt();
}
in.close();
for(int i=n-1; i >=0; i--) {
System.out.print(arr[i] + " ");
}
}
}
```
