HackerRank Day 7 Solution in Python

#!/bin/python3

import math
import os
import random
import re
import sys

if __name__ == '__main__':
    #Number of array elements
    n = int(input().strip())
    
    #Get Array elements
    arr = list(map(int, input().rstrip().split()))
    # reverse the array with list slicing
    rev_arr = arr[::-1]  
    #Print the reversed array
    for i in rev_arr:
        print(i, end=" ")

Explanation

First, we get the array elements as the input
Then, we use list slicing to reverse the array and store the reversed array in a new array
Then, we print the reversed array elements
