How to find middle element in linked list using C?

Traverse linked list using two pointers. Move one pointer by one and the other pointers by two. When the fast pointer reaches the end slow pointer will reach the middle of the linked list.

How do you find the middle element of a linked list in a single iteration?

In each iteration, the ptr1 will access the two nodes and the ptr2 will access the single node of the linked list. Now, when the ptr1 reaches the end of the linked list, the ptr2 will be in the middle. In this way, we are able to get the middle of linked list in a single iteration.

How do you find the middle element of a linked list without traversal?

To find the middle element of a linked list, there are two possible approaches: Iterate the list of elements once and count the number of nodes in the list. Once again iterate through the list this time only till the (count/2) position. The element at position (count/2) is the middle element.
