Double Insertion Sort is a variation on Insertion Sort that works from the middle of the array out. At each iteration, some middle portion of the array is sorted. On the next iteration, take the two adjacent elements to the sorted portion of the array. If they are out of order with respect to each other, then swap them. Now, push the left element toward the right in the array so long as it is greater than the element to its right. And push the right element toward the left in the array so long as it is less than the element to its left. The algorithm begins by processing the middle two elements of the array if the array is even. If the array is odd, then skip processing the middle item and begin with processing the elements to its immediate left and right. Implement Double Insertion Sort, being careful to properly handle both when the array is odd and when it is even.Improved Bubble Sort: One possible improvement for Bubble Sort would be to add a ﬂag variable and a test that determines if an exchange was made during the current iteration. If no exchange was made, then the list is sorted and so the algorithm can stop early. This makes the best-case performance become O(n) (because if the list is already sorted, then no iterations will take place on the ﬁrst pass, and the sort will stop right there). Modify the Bubble Sort implementation to add this ﬂag and test.
