Slow fast pointer
Webb1 apr. 2024 · The middle of linked list can be found using the slow-fast pointer approach. To avoid an extra pass, we can also reverse the first half side by side while we find the middle element. We have two cases - Linked list is even length - There will be two middle elements(say e1 & e2) and at end of iteration, our slow pointer will end at e1.
