Middle of Linked List
Detailed guide and Python implementation for the 'Middle of Linked List' problem.
Problem Statement
Write a function middle_node(arr) that represents a singly linked list as a Python list arr and returns the sublist starting from the middle node. If there are two middle nodes (even length), return the sublist starting from the second middle node.
- •1 <= len(arr) <= 1000
- •-1000 <= arr[i] <= 1000
Examples
arr = [1, 2, 3, 4, 5]
[3, 4, 5]
The middle node is 3, so we return the list from 3 onwards.
arr = [1, 2, 3, 4, 5, 6]
[4, 5, 6]
The middle nodes are 3 and 4; we return the list from the second middle node 4.
