Question

this is the template to be user. Add the code here according to the question in image. in java language.

public class MergeSort {

ArrayList getInput(ArrayList<Integer> al) { // }

void getOutput(ArrayList<Integer> al) { // }

void merge(ArrayList<Integer> al, int beg, int mid, int end) { // }

void sort(ArrayList<Integer> al, int beg, int end) { // }

public static void main(String[] args) { // TODO Auto-generated method stub }

}

Requirements: • You have to strictly Use ArrayList for this. • You have to Implement the concept of class and object. • You have to create a separate method for input and output. • Main method should not be used to get input or output. To understand merge sort, we take an unsorted array as the following - 14 33 27 10 35 19 | 42 44 We know that merge sort first divides the whole array iteratively into equal halves unless the atomic values are achieved. We see here that an array of 8 items is divided into two arrays of size 4. 14 33 27 10 35 19 42 44 This does not change the sequence of appearance of items in the original. Now we divide these two arrays into halves. 14 33 27 10 35 19 42 44 We further divide these arrays and we achieve atomic value which can no more be divided. 14 33 27 10 35 19 42 44 Now, we combine them in exactly the same manner as they were broken down. Please note the color codes given to these lists. We first compare the elements for each list and then combine them into another list in a sorted manner. We see that 14 and 33 are in sorted positions. We compare 27 and 10 and in the target list of 2 values we put 10 first, followed by 27. We change the order of 19 and 35 whereas 42 and 44 are placed sequentially.

14 33 10 27 19 35 42 44 In the next iteration of the combining phase, we compare lists of two data values, and merge them into a list of found data values placing all in a sorted order. 14 27 33 42 44 10 19 35 After the final merging, the list should look like this - 10 14 19 27 33 35 42 44 Now we should learn some programming aspects of merge sorting. Algorithm Merge sort keeps on dividing the list into equal halves until it can no longer be divided. By definition, if there is only one element in the list, it is sorted. Then, merge sort combines the smaller sorted lists keeping the new list sorted too. Step 1 - if it is only one element in the list it is already sorted, return. Step 2 - divide the list recursively into two halves until it can no longer be divided. Step 3 - merge the smaller lists into new lists in sorted order.
