How to Reverse a Linked List in Python
One common programming interview question is how to implement a function to reverse a linked list in Python. Here's a simple implementation:
```python
class Node:
def __init__(self, value):
self.value = value
self.next = None
def reverse_linked_list(head):
prev = None
current = head
while current:
next_node = current.next
current.next = prev
prev = current
current = next_node
return prev
```
This function, reverse_linked_list
, takes the head of the linked list as input and reverses the order of the elements in the list. It iterates through the list, keeping track of the previous node and updating the links accordingly.
Now you can use this function to reverse a linked list in Python for your programming interviews!
