Which one of the following sequences when stored in an array at locations A[1],..., A[10] forms a max-heap?

23, 17, 10, 6, 13, 14, 1, 5, 7, 12
23, 17, 14, 7, 13, 10, 1, 5, 6, 12
23, 17, 14, 6, 13, 10, 1, 5, 7, 15
23, 14, 17, 1, 10, 13, 16, 12, 7, 5

Correct answer: 23, 17, 14, 7, 13, 10, 1, 5, 6, 12

Solution

This sequence satisfies the max-heap property where each parent node is greater than or equal to its child nodes, ensuring that the largest element is at the root and all levels of the heap maintain this order.

Let SLLdel be a function that deletes a node in a singly-linked list given a pointer to the node and a pointer to the head of the list. Similarly, let DLLdel be another function that deletes a node in a doubly-linked list given a pointer to the node and a pointer to the head of the list. Let n denote the number of nodes in each of the linked lists. Which one of the following choices is TRUE about the worst-case time complexity of SLLdel and DLLdel?
