Given the following integer elements: 30, 65, 22, 40, 15, 70, 80, 60, 55, 10 For a and b Show all intermediate steps for full credit. You do not need to show the array representation of the heap.

a. Draw the tree representation of the heap that results when all of the above elements are added (in the given order) to an initially empty maximum binary heap. Circle the final tree that results from performing the additions.

b. After adding all the elements, perform 2 removes on the heap. Circle the tree that results after the two elements are removed.

If an improvement creates no significant change in a product’s performance, then it is a(n) ? a0 design improvement. (there are no answer choices)

Use a physical stopwatch to record the length of time it takes to run the program. calculate the difference obtained by calls to the method system. currenttimemillis() just before the start of the algorithm and just after the end of the algorithm. calculate the difference obtained by calls to the method system. currenttimemillis() at the start of the program and at the end of the program so that the elapsed time includes the display of the result. use the value returned by the method system. currenttimemillis() just after the end of the algorithm as the elapsed time.
