Try to solve the Reverse Linked List problem.

Statement

Given the head of a singly linked list, reverse the linked list and return its updated head.

Constraints:

Let n be the number of nodes in a linked list.

  • 1≤1 \leq n ≤5×102\leq 5\times10^2
  • −5×103≤-5\times10^3 \leq Node.value ≤5×103\leq 5\times10^3

Try it yourself

Implement your solution in the following coding playground.

Python
usercode > main.py
from ds_v1.LinkedList.LinkedList import LinkedListNode



# class LinkedListNode:

#     def __init__(self, data):

#         self.data = data

#         self.next = None



def reverse(head):



    # Replace this placeholder return statement with your code

    return head
