1. Which of the following is a proper array representation a binary min heap?2. A heap is implemented using an array. At what index will the right child of node at index i be found? Note, the Oth position of the array is not used.Select one:a. i/2b. 2 i+1c. i-1d. 2 i3. Consider the following array of length 6. Elements from the array are added, in the given order, to a max heap. The heap is initially empty and stored as an array.A={18,5,37,44,27,53}What...

5. A three-heap with n elements can be stored in an array A, where A[O] contains the root of the tree. a) Draw the three-heap that results from inserting 5, 2, 8, 3, 6, 4, 9, 7, 1 in that order into an initially empty three-heap. You do not need to show the array representation of the heap. You are only required to show the final tree, although if you draw intermediate trees. b) Assuming that elements are placed in...

Consider the following complete binary tree is stored in an array the way we learned during heap lecture. The root node is stored at index 1. The last node (47) is stored at index heapsize. If you want to build a heap from the array using the heapify(), what position of the array you start doing percolate Down in heapify()? Answer: What is the run-time to build a heap from an array of size n using heapify() process ? OC...

1. In a heap, the upper bound on the number of leaves is: (A) O(n) (B) O(1) (C) O(logn) (D) O(nlogn) 2. In a heap, the distance from the root to the furthest leaf is: (A) θ(nlogn) (B) θ(logn) (C) θ(1) (D) θ(n) 3. In a heap, let df be the distance of the furthest leaf from the root and let dc be the analogous distance of the closest leaf. What is df − dc, at most? (A) 1 (C)...

(c) Draw the binary heap structure that is equivalent to the following list (the root is first element). [5, 9, 8, 12, 15, 11, 19, 14, 20, 18, 17, 13] [4 marks] (d) Show the resulting tree after the value 6 is added to the heap in the part (c). Note that the binary heap properties must be restored after insertion. Show your working; you may show the data structure in tree or array form. [3 marks]

In the lectures, we studied binary heaps. A min-Heap can be visualized as a binary tree of height with each node having at most two children with the property that value of a node is at most the value of its children. Such heap containing n elements can be represented (stored) as an array with the property Suppose that you would like to construct a & min Heap: each node has at most& children and the value of a node...

6. T or F: There can be two or more nodes in a heap with exactly one child. 7. T or F: A heap can have no nodes with exactly one child. 8. T or F: All heaps are perfect trees. 9. T or F: No heaps are perfect trees. 10. T or F: All heaps are complete trees. 11. T or F: No heaps are complete trees. 12. T or F: A binary tree with one node must be...

Problem 8. (Heap Top-k) Prof Dubious has made the following claim, and has provided a proof Claim. Let n and k be positive integers such that 2*-1n. In amax-heap H of n elements, the top 21 elements are in the first k layers of the heap. Proof. Since is a max-heap, each node in H must satisfy the heap property, i.e., if H, is an element of H with at least one child then Hmaxchldren(H)). We know that every subtree...

A heap can be encoded either as an array, or as a full binary tree. For this question, write a function that takes the array representation of a heap and outputs its binary tree representation. More specifically, you should write a function with the specifications given below. Specifications for the function: # def arrayToTree(A, j): # input: array A representing a heap, an index j in [0:len(A)] # output: a Node object storing the heap with root j in the...

Consider the min-priority queue implemented by a binary heap. (The max-priority queue is treated in §6.5 Priority queues in the textbook.) Show the binary tree implemented by the array A = 〈5, 8, 9, 11, 10, 12, 10, 12, 15, 11, 14, 13, 16, 15〉. Show the binary tree resulting from Heap-Insert(A, 6) where A is the array in (a). Show the binary tree resulting from Extract-Min(A) where A is the array in (a). Show the binary tree resulting from...
