The Binary Search algorithm works by testing a mid-point, then eliminating half of the list. In this exercise, you are going to take our binary search algorithm and add print statements so that you can track how the search executes. Inside of the recursive binary search function, add print statements to print out the starting, ending, and midpoint values each time. Then as you test a value, print out the results, either too high, too low, or a match. Sample Output Starting value: 0 Ending value: 9 Testing midpoint value: 4 Too high! Starting value: 0 Ending value: 3 Testing midpoint value: 1 Too low! Starting value: 2 Ending value: 3 Testing midpoint value: 2 Match!
Both Quicksort and Insertionsort have the time complexity O (n2) in the worst case. Which of the following statements is correct? A. Place of insertion is faster than average Quicksort, regardless of the value of 'n'. B. Choosing the first element as a pivot is a very effective strategy for Quicksort. C. Both Quicksort and Insertion sort are usually implemented as recursive algorithms. D. Insertion sort is generally faster than Quicksort for smaller values of n (<20 elements).

Consider the following list: 2, 20, 38, 41, 49, 56, 62, 70, 88, 95, 100, 135, 145 Using a sequential search on ordered lists, that you designed in (a), how many comparisons are required to determine whether the following items are in the list? (Recall that comparisons mean item comparisons, not index comparisons.) (1, 2) 2 57 88 70 135 Write a program to test the function you designed. Note: Have the function,seqOrdSearch, return -1 if the item is not found in the list. (return the index of the item if found).
Language: C++ Write a Program with Comments for your code to improve quick sort. The quick sort algorithm presented in the ClassNotes-Sorting, it selects the first element in the list as the pivot. Revise it by selecting the median among the first, middle, and last elements in the list.Explain your Outputs or Answers for the following: (C) Give a list of n items (for example, an array of 10 integers) representing the worst-case scenario. (D) Give a list of n items (for example, an array of 10 integers) representing the best-case scenario. Please compile your answers in a file including all source code with comments, Explain your running Outputs or Answers in (A) ~(D). Quicksort that was mentioned in the ClassNotes: #include <iostream>using namespace std; // Function prototypesvoid quickSort(int list[], int arraySize);void quickSort(int list[], int first, int last);int partition(int list[], int first, int last); void quickSort(int list[], int arraySize){quickSort(list, 0,…
the language is C++, please take a screenshot of your output. (Recursive binary search) The binary search algorithm given in this chapter is nonrecursive. Write and implement a recursive version of the binary search algorithm. Also, write a version of the sequential search algorithm that can be applied to sorted lists. Add this operation to the class orderedArrayListType for array-based lists. Moreover, write a test program to test your algorithm.

The program will read a list of one word names, then use a recursive method to create and output all possible orderings of those names, one ordering per line. When the input is: Julia Lucas Mia then the output is (must match the below ordering): Julia Lucas Mia Julia Mia Lucas Lucas Julia Mia Lucas Mia Julia Mia Julia Lucas Mia Lucas Julia

You were tasked to do programs that will illustrate the use of lists implemented using an array. One uses a sorted list, the other an unsorted list. Run the programs separately and answer the following questions. Write a program that will initially create an UNSORTED list containing the following and then run the program: Mitch Diane Jack Robbie Katherine Answer and explain the following questions below: Ifwecheckthememorylocationofeachelementinthelist,whatwoulditbe?What index represent eachelement? What happens if we add Morrie in the list? What will be its indexvalue? Whatdoesthenewlistlooklike?WheredoyouthinkMorrieshouldbeplacedand why? With the same list above (with Morrie added), delete/remove Jack. Answer and explain the following questions below: What is the new list? Identify the elements of the list and itsindex.

7) Implement counting sort over a list of keys that lie within the range (a, b),where a and b are small positive integers input by the user.8) Implement bucket sort with an array of lists data structure to sort i) a list ofstrings, ii) a list of floating point numbers and iii) a list of integers, which areuniformly distributed over a range, for an appropriate choice of the number ofbuckets.
Answer the given question with a proper explanation and step-by-step solution. (Java) Write methods called sum and average that return the sum of all values in the list and the average value as a real number, respectively. For example, if a variable called list stores [11, –7, 3, 42, 0, 14], the call of list.sum() should return 63 and the call of list.average() should return 10.5. If the list is empty, sum should return 0 and average should return 0.0.
