Compare the efficiency of the Merge Sort and Selection Sort algorithms.
Homework Answers
The best,average and worst case complexity of merge sort is
O(nlogn)
The best,average and worst case complexity of Selection sort is
O(n^2)
so, in terms efficiency merge sort is better compare to selection
sort
Merge sort keep on divides the list into two equal halfs, then
merges it into sorted list, this process reduces the number of
comparisions
selection sort repeatedly finds min from the remaining list, then
places it in correct position,leads to higher number of
comparisions than merge sort

This question involves comparing the sorting algorithms that we studied so far such as selection sort, bubble sort, insertion sort, merge sort & quicksort. First briefly explain the idea behind each of them. And then compare them according to the criterion such as time (best, worst and average case) and space efficiency, stability, applicability (when performs best) etc. You may use following links as hints, however you will be able to find a significant number of links that compare sorting...

Implement and compare sorting algorithms. The task is to sort a list of integers using 5 sorting algorithms: selection sort insertion sort merge sort heap sort quicksort Your program should include 5 separate sorting methods, though it is fine for them to call some common methods (like "swap") if needed. Each sorting method should also count the number of comparison operations and assignment operations on the array elements during the sorting process. In the main program, two types of array...
