Web3. Delete the Last Node of Doubly Linked List. In this case, we are deleting the last node with value 3 of the doubly linked list. Here, we can simply delete the del_node and make the next of node before del_node point to NULL. Reorganize the pointers. The final doubly linked list looks like this. Final list. Code for Deletion of the Last Node WebMar 19, 2024 · The great tree-list recursion problem. A binary search tree and a circular doubly linked list are conceptually built from the same type of nodes - a data field and two references to other nodes. Given a binary search tree, rearrange the references so that it becomes a circular doubly-linked list (in sorted order).
