Consider a computer that has a number of registers such that the three registers r0 = 1500, r1 = 4500, and r2 = 1000. show the effective address of memory and the registers’ contents in each of the following instructions (assume that all numbers are decimal).
(a) add (r0)+, r2
(b) subtract - (r1), r2
(c) move 500(r0), r2
(d) load #5000, r2
(e) store r0, 100(r2)

Write a method in the heapintpriorityqueue class called merge that accepts another heapintpriorityqueue as a parameter and adds all elements from the other queue into the current queue, maintaining proper heap order such that the elements will still come out in ascending order when they are removed. your code should not modify the queue passed in as a parameter. (recall that objects of the same class can access each other's private fields.)
