WebSo you optimize the additional O (n) memory usage to O (1) The best way to sort doubly linked lists I'm aware of is to use natural mergesort. You start by splitting the list first to sorted sublists by traversing it once and finding sorted list sequences. These sorted sublists are linked together with backward-pointers of the elements to avoid ... WebBuilding circular linked list. Building a circular linked list is not at as hard as it sounds from the name. So far, we have seen that adding a new node at the end is pretty simple; we set the next reference of the last node to NULL.In a circular linked list, the last node's next reference will actually point to the first node, thereby creating a circular list.
