1.3 Which of the following is true about sorting functions?A.The most optimal partitioning policy for quicksort on an array we know nothing about wouldbe selecting a random element in the array.B.The fastest possible comparison sort has a worst case no better than O(n log n).C.Heapsort is usually best when you need a stable sort.D.Sorting an already sorted array of size n with quicksort takes O(n log n) time.E.When sorting elements that are expensive to copy, it is generally best to use merge sort.F.None of the above statements is true.
Homework Answers

(5 marks; questions to Reza) In Lecture 5, Travis said you can prove QuickSort takes N(n log n) time in the best case the same way he proved any comparison-based sorting algorithm takes (n log n) time in the worst case. Give that proof. Notice it doesn't follow directly: e.g., Insertion Sort takes O(n) time in the best case. You can assume QuickSort divides each array into elements less than or equal to the pivot (including the pivot itself) and...

Data Structures: For each of the following situations, name the best sorting algorithm we studied. (For one or two questions, there may be more than one answer deserving full credit, but you only need to give one answer for each.) (a) The array is mostly sorted already (a few elements are in the wrong place). (b) You need an O(n log n) sort even in the worst case and you cannot use any extra space except for a few local...

A test harness program for testing sorting methods is provided with the rest of the textbook program files. It is the file Sorts.java in the ch11 package. The program includes a swap method that is used by all the sorting methods to swap array elements. Describe an approach to modifying the program so that after calling a sorting method the program prints out the number of swaps needed by the sorting method. Implement your approach. Test your new program by...
