Program to print the elements of an Array in Reverse order

What is an Array?

An array is a collection of similar data elements stored at contiguous memory locations. It is the simplest data structure where each data element can be accessed directly by only using its index number.

What to do in this program :

In this program, we need to print the elements of the array in reverse order that is; the last element should be displayed first, followed by second last element and so on.

Above array in reversed order:

Source code :

     
arr = [1, 2, 3, 4, 5];     
print("Original array: ");    
for i in range(0, len(arr)):    
    print(arr[i]),     
print("Array in reverse order: ");    
    
for i in range(len(arr)-1, -1, -1):     
    print(arr[i]),

Source code explanation:

step 1 :Initialize array
arr = [1, 2, 3, 4, 5];
print(“Original array: “);
for i in range(0, len(arr)):
print(arr[i]),
print(“Array in reverse order: “);
step 2 :Loop through the array in reverse order
for i in range(len(arr)-1, -1, -1):
print(arr[i]),

Output :

Python 3.7.4 (tags/v3.7.4:e09359112e, Jul  8 2019, 19:29:22) [MSC v.1916 32 bit (Intel)] on win32

First the program print the original array.
Then by applying loop reverses it.

Conclusion :

The program is running fine.
