Question 4
Programming Language: Dr. Racket (R5RS) Question: (a) Define a SCHEME procedure, named (heap-insert f x H), which adds element x to heap H using the first-order relation f to determine which element belongs at the root of each (sub)tree.For instance, if we wanted the same behavior as the heaps in the lecture slides (min-heap), we would use the “less than” function as our first-order relation: (heap-insert < 100 (heap-insert < 10 (list))) (10 () (100 () ()))

4) Built a Binary Search Tree with the following integers given in order: 14 17 97 11 16 19 5 18 20 a. Compute the height of the obtained tree. b. Is the obtained BST Complete, Full or Perfect? Justify your answer. What are the nodes which should be deleted to transform the tree into a complete c. one. d. To transform this tree into a Full Binary Search Tree, we suggest to insert 8 or 10. What is the best choice? Why?
Please answer ASAP The insert function below is used to insert item into the priority queue and maintaining the heap order property. (Note: isFull and Overflow functions are defined elsewhere and work properly) Explain what are lines 1 to line 4 doing. template void BinaryHeap::insert(const Comparable & x) { if (isFull()) throw Overflow(); int hole = ++currentSize; // line 1 for ( ;hole > 1 && x < array[hole/2]; hole /= 2) // line 2 array[hole] = array[hole/2]; // line 3 array[hole] = x; // line 4 }
