The below plots of computational costs (representative of execution time) of the TreeSort and HeapSort algorithms are typical. TreeSort and HeapSort are the algorithms we discussed in our lectures: TreeSort uses a binary search tree, and HeapSort uses a binary heap. The graphs were generated from actual runs of sorting for randomly generated vectors of integers; data points are the averages of sorting performances for 25 vectors each for data sets of sizes 10 to 50. 400 350 300 250 200 150 100 50 0 10 15 20 25 30 Your answer here: 50 45 35 40 -TreeSort -HeapSort -NlogN In the diagram, the cost of Heapsort is consistently lower than the cost of TreeSort. Exp 1-3 sentences why it will always be the case that on average HeapSort will be more effi than TreeSort.
