I tried traversing to the next element from the starting node and the previous element from the end node and check if the reference of both is same or not. Number one, who still uses linked lists ; Two, finding the middle node is an arbitrary, academic exercise with no value in real-life scenarios; Three, if I really needed to know the middle node, my linked list would expose a node count.

If you update reference to current every second time, nothing good will come out of this. Yes we can find middle element of a singly linked list in single pass. So you know where halfway is, anyway.

algorithm to find middle element of linked list @ O(n/2) order

In this tutorial, We are going to explain how to find middle element of a linked list in Java. This programming question is mostly asked in a technical interviews. For example: Given a linked list, the middle element in this linked list is 8. In this tutorial, We are going to learn two approaches through which we can find middle element of a singly linked list. Also, i have also added video tutorial at the end of this tutorial. How to Find Middle Element of a Linked List. Method 1: i Traverse and find the length of a linked list. Can we do better than that. Yes we can find middle element of a singly linked list in single pass. Method 2: Find middle element of a linked list in single traversal.

But thank you for at least stating a reason. This problem almost the same as the. For example, you can have two node variables to have middle node values, let mid1 and mid2 in case of even number of total nodes you will have two middle nodes. I didn't thought that I can use two pointers or two variables to keep track of middle and last item, something I missed. Your algorithm does not appear to work - it always returns the third to last element in the list, I believe, not the middle element. Maybe my mind is still not awaken after Christmas laziness, but.
