Given аn unsоrted аrrаy A оf n distinct integers and an integer k, yоu need to return the k smallest integers in the array in sorted order, where k may be any integer between 1 and n. Suppose that you have the following three algorithms to solve this problem. A1: Sort the array in increasing order, then list the first k integers after sorting. A2: Build a min-heap from these n integers, then call Extract-Min k times. A3: Use the linear time selection algorithm to find the k-th smallest integer in the array, then partition the array about that number to obtain the k smallest numbers in the array, and finally sort the k smallest numbers. Assume that you are using mergesort as your sorting algorithm, and use the linear time build-heap algorithm to build the heap. Let T1(n, k) denote the worst-case running time of Algorithm A1. Let T2(n, k) denote the worst-case running time of Algorithm A2. Let T3(n, k) denote the worst-case running time of Algorithm A3. Analyze the worst-case running times of the algorithms. What is the asymptotic notation for T2(n, k)? Use the most accurate big-O notation in your answer. Note that k is between 1 and n. Hence k is nominated by n.
Write а cоmplete Jаvа prоgram named CalculateCоst. It receives the name of a customer as a console argument. It then prints a welcome message and asks for the number of products the customer is buying. After that, it accepts a list of products (one per line) that the customer wishes to buy. The product options a user can enter per line are "pen" or "pencil". A pen costs $2, and a pencil costs $1.25. The program prompts for products until it has received the exact number of products provided by the user in the first prompt. After the list, the program prints the final line with the cost after taxes (the tax is 4% of the cost before tax). The cost should be rounded to two decimals. Your output must look exactly like the example. The final line must be printed in its entirety with a single printf Example command: java CalculateCost Max. Example console input/output (input in bold):Hello Max!Please enter the number of products: 3pencilpenpencil
