1. Find middle node of a Linked List
Easy
20m average time
80% success
0/40
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
1: Take two pointers (slow and fast) pointing to head.
2: Move slow to next and fast to next->next.
3: Compare when slow=fast then it is the middle node.
