Given section of mergeSort code,will fall in infinite
Loop.
Because it keeps on calling mergeS() function before checking
condition
if(st==en) return;
Therefore this code keeps on calling mergeS() function until stack overflows.

In this assignment you will implement merge-sort algorithm by creating 2 threads instead of 2 processes. First half of the array will be sorted by thread 1 and the second half by thread 2. When the threads complete their tasks, the main program will merge the half arrays. You should not waste your time on merge-sort algorithm. Use the merge sort algorithm given below void mergesort(int a[],int i,int j) { int mid; if(i<j) { mid=(i+j)/2; mergesort(a,i,mid); //left recursion mergesort(a,mid+1,j); //right...

must provide the following public interface: public static void insertSort(int [] arr); public static void selectSort(int [] arr); public static void quickSort(int [] arr); public static void mergeSort(int [] arr); The quick sort and merge sort must be implemented by using recursive thinking. So the students may provide the following private static methods: //merge method //merge two sorted portions of given array arr, namely, from start to middle //and from middle + 1 to end into one sorted portion, namely,...

Modify the sorts (selection sort, insertion sort, bubble sort, quick sort, and merge sort) by adding code to each to tally the total number of comparisons and total execution time of each algorithm. Execute the sort algorithms against the same list, recording information for the total number of comparisons and total execution time for each algorithm. Try several different lists, including at least one that is already in sorted order. ---------------------------------------------------------------------------------------------------------------- /** * Sorting demonstrates sorting and searching on an...
