Reversing an Array

Category: Python Libraries For Data Science

Write a NumPy program to reverse an array (first element becomes last). Return the reversed array.

Example 1:

Input: np.array([1, 2, 3, 4, 5]) 
Output: array([5, 4, 3, 2, 1])

Example 2:

Input: np.array([10, 20, 30, 40, 50]) 
Output: array([50, 40, 30, 20, 10])

You can use array slicing to reverse an array.

import numpy as np

def reverse_array(array):
    return array[::-1]

print(reverse_array(np.array([1, 2, 3, 4, 5])))
print(reverse_array(np.array([10, 20, 30, 40, 50])))
