Final answer:
The question requires writing a function that reverses a list of n elements in place. This is typically done by swapping elements from opposite ends of the list until the center is reached, without creating a new list.
Step-by-step explanation:
The question is asking for a method to reverse a list of n elements in place within a function, without creating a new list. To achieve this in programming, one would typically write a function that swaps the elements of the list starting from the ends and moving towards the center. Here's a generic example in Python:
def reverse_list(lst):
left_index = 0
right_index = len(lst) - 1
while left_index < right_index:
lst[left_index], lst[right_index] = lst[right_index], lst[left_index]
left_index += 1
right_index -= 1
By calling this function with your list, the elements of the list will be reversed in place. This means that no additional space is used, which would be the case when creating a new reversed list. The in-place reversal is efficient and maintains the original list's memory address.
