1. # Get list length.
2. L = len(numbers)
3. # i goes from 0 to the middle.
4. for i in range(int(L/2)):
5. # Swap each number with the number in.
6. # the mirror position for example first.

3. Move head node to its next node i.e. head = head->next.

How do you print a list in reverse order in python for loop?

6. Python program to print the elements of an array in reverse order

1. STEP 1: Declare and initialize an array.
2. 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.
3. STEP 3: Print the element arr[i] in each iteration.
