Question

An integer matrix is an n×m array of integers; for example:

a)Write pseudocode for this modied version of insertion sort (call it MatrixInsertionSort) .I dnt want simple insertion sort.

b)Prove the best- and worst-case complexity of MatrixInsertionSort. Matrix is square matrix

c) If comparing two rows take constant time O(1) . Is the worst-case complexity of MatrixInsertionSort in this case better or worse than regular insertion sort? Why?

3 10 1 1012-18 A=13-12-101 670 -23 3 10 5 A row is a series of numbers from left to right and a column is the series from top to bottom. Here, we will modify insertion sort to sort the rows of a matrix, with respect to their colums. For the above example, this yields: [1 1012 -18 3 -12-101 A=13 10 3 105 67 0 -23

Explanation / Answer

The implementation of Insertion Sort on an integer array. Insertion sort is a simple sorting algorithm that builds the final sorted array (or list) one item at a time. It is much less efficient on large lists than more advanced algorithms such as quicksort, heapsort, or merge sort. However, advantages of Insertion Sort are that it is efficient for (quite) small data sets, adaptive for data sets that are already substantially sorted, stable (i.e. does not change the relative order of elements with equal keys), In-place ( i.e. only requires a constant amount O(1) of additional memory space) .

Worst case performance : (n2) comparisons, swaps
Best case performance : O(n) comparisons, O(1) swaps
Average case performance : (n2) comparisons, Swaps.
