(Enhanced Bubble Sort) Make the following simple modifications to improve the perfor- mance of the bubble sort you developed in Exercise 19.5:

a) After the first pass, the largest value is guaranteed to be in the highest-numbered element of the vector; after the second pass, the two highest values are “in place”; and soon. Instead of making nine comparisons (for a 10-element vector) on every pass, modify the bubble sort to make only the eight necessary comparisons on the second pass, seven on the third pass, and so on. b) The data in the vector may already be in the proper order or near-proper order, so why make nine passes (of a 10-element vector) if fewer will suffice? Modify the sort to check at the end of each pass whether any swaps have been made. If none have been made, the data must already be in the proper order, so the program should terminate. If swaps have been made, at least one more pass is needed.
