Asked in companies
Given a singly linked list of 'N' nodes. The objective is to determine the middle node of a singly linked list. However, if the list has an even number of nodes, we return the second middle node.
Note:
1. If the list is empty, the function immediately returns None because there is no middle node to find.
2. If the list has only one node, then the only node in the list is trivially the middle node, and the function returns that node.
Problem approach
Given a singly linked list of N nodes.
The task is to find the middle of the linked list. For example, if the linked list is
1-> 2->3->4->5, then the middle node of the list is 3.
If there are two middle nodes(in case, when N is even), print the second middle element.
For example, if the linked list given is 1->2->3->4->5->6, then the middle node of the list is 4.
