- Write a procedure that, given parameters A, n, and i, where A is the array representation of an n-element heap, and 1 ≤ i ≤ n, deletes the element A[i] from the heap in O(log n) tim e.arrow_forward3. Sort the array A= [10, 15, 11, 12, 6, 28, 19] by using the operation (insertion and deletion) of Heapsort.arrow_forwardConsider the following array representation of a complete binary tree in python.

- Consider an array: 4,2,9,1,7,8,6,3,5. Show all the steps of Heap sort.arrow_forwardmultiple choice: consider an array based implementation of a stack and its push operation. Beginning with an array of length 1 = (2^0), consider where the array’s length will be doubled whenever an insertion(via the push operation) is attempted when the array is full. What is the amortized complexity of performing a sequence of n push operations. a) Θ(log n) b) Θ(n) c) Θ(n^2) d) Θ(1)arrow_forwardOutline an algorithm in pseudo code for checking whether an array H[1..n] is a heap and determine its time efficiency.arrow_forward
- Python and a graph Implement the heap-sort algorithm. Experimentally compare its running time with that of insertion sort and the built-in Python sorted function. You could use dummy functions with O(n^2) and O(nlogn) and use them as benchmarks in your graph. Results: 1. A graph showing the curves for heap-sort, insertion sort, and built-in the sorted function. 2. code that generates the data used in the graph.arrow_forwardGiven the array [5, 3, 7, 2, 4, 6, 8].Write an approach to sort an array of integers using a binary search tree (BST). Discuss the time complexity of your approach.arrow_forwardShow that: In Stack's implementation of resizing arrays, the worst-case scenario average number of array accesses for any sequence of actions beginning with an empty data structure is constant.arrow_forward
- Describe a fast recursive algorithm for reversing a singly linked list L, sothat the ordering of the nodes becomes opposite of what it was before. Code and describe each code.arrow_forward4. Given an array, arr[] = {90, 15, 10, 7, 12, 2), does this array represents a Max-Heap? if it does, draw this max-heap.arrow_forwardMultiple Choice: Select one only: Suppose we cannot use a priority queue (either due to unavailability of libraries, or constraints on operations). If we still want to implement Dijkstra’s algorithm, we must look for the “next closest vertex” by iterating across all vertices and storing distance data on an array, instead of letting the priority queue find this efficiently for us. What would then be the time complexity of this version of Dijkstra’s algorithm without priority queues? a. O(V^2) b. O(V+E) c. O(VE) d. O(VElogV)arrow_forward
