Challenge: Inversing the Order of Elements in the List
Swipe to start coding
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
andcurrent
, wherecurrent
traverses the list andprev
points to the previous node.
At each step,current
's next pointer is updated to point toprev
, effectively reversing the list. Finally,prev
becomes the new head of the reversed list, returned by the function.
