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:

ALGORITHM:

  • STEP 1: Declare and initialize an array.
  • STEP 2: Loop through the array in reverse order that is, the loop will start from (length of the array - 1) and end at 0 by decreasing the value of i by 1.
  • STEP 3: Print the element arr[i] in each iteration.

#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: ");    
#Loop through the array in reverse order    
for i in range(len(arr)-1, -1, -1):     
    print(arr[i]),

 

Output:

Original array: 
1	2   3   4   5
Array in reverse order:
5    4   3   2   1
