bookChallenge: Inversing the Order of Elements in the List

Task

You are given a singly linked list. Your task is to write following Python functions:

  • the function that creates linked list;
  • the function that prints values of the linked list;
  • the function that reverses the order of the elements in the linked list.

Note

The reverse_linked_list() function iterates through the linked list while updating pointers to reverse the direction of nodes.
It maintains two pointers, prev and current, where current traverses the list and prev points to the previous node.
At each step, current's next pointer is updated to point to prev, effectively reversing the list. Finally, prev becomes the new head of the reversed list, returned by the function.
