Data Structure & Algorithm: Show by fully java coded examples how any two sorting algorithms work. You should test these with various array sizes and run them several times and record the execution times. At least four array sizes are recommended. 15, 20, 25, 30. It is recommended you write the classes and then demonstrate/test them using another class. Discuss the comparative efficiencies of your two chosen sorting algorithms.

In java there must be at least two calls to the function with different arguments and the output must clearly show the task being performed. (ONLY ARRAYS or ARRAYLIST) Develop a function that accepts an array and returns true if the array contains any duplicate values or false if none of the values are repeated. Develop a function that returns true if the elements are in decreasing order and false otherwise. A “peak” is a value in an array that is preceded and followed by a strictly lower value. For example, in the array {2, 12, 9, 8, 5, 7, 3, 9} the values 12 and 7 are peaks. Develop a function that returns the number of peaks in an array of integers. Note that the first element does not have a preceding element and the last element is not followed by anything, so neither the first nor last elements can be peaks. Develop a function that finds the starting index of the longest subsequence of values that is strictly increasing. For example, given the array {12, 3, 7, 5, 9, 8,…

Classes, Objects, Pointers and Dynamic Memory Program Description: This assignment you will need to create your own string class. For the name of the class, use your initials from your name. The MYString objects will hold a cstring and allow it to be used and changed. We will be changing this class over the next couple programs, to be adding more features to it (and correcting some problems that the program has in this simple version). Your MYString class needs to be written using the .h and .cpp format. Inside the class we will have the following data members: Member Data Description char * str pointer to dynamic memory for storing the string int cap size of the memory that is available to be used(start with 20 char's and then double it whenever this is not enough) int end index of the end of the string (the '\0' char) The class will store the string in dynamic memory that is pointed to with the pointer. When you first create an MYString object you should…
python: numpy def coupons(my_list, on_sale, prices): ''' QUESTION 5 It's the time of week to go grocery shopping again! Given three arrays, one of what's on sale, one of your own list, and one of the prices, return an array of the items on your list that are on sale and more than five dollars. You have MORE coupons than you have groceries on your list- make sure to only use the coupons that correspond to your list. THIS MUST BE DONE IN ONE LINE Hint: use masking and slicing Args: my_list(np.array) on_sale(np.array) prices(np.array) Return: np.array >>> my_list = np.array(["eggs", "2% milk", "green onions", "whole wheat bread", "onions", "spinach", "peanut butter", "boxed spaghetti", "salt and vinegar chips", "alfredo sauce"]) >>> on_sale = np.array([True, False, True, True, True, True, False, False, False, True, False, True, False])…
