Assume that there is a priority queue consisting of 6 items. Their arriving orders and priority values are as follows: Arriving Sequence Symbol Priority Value R 6 2 X 3 3 H 1 4 U 5 s S 2 6 T 4 Suppose that the priority queue is implemented by using tree nodes. Draw the priority queue. Suppose that the priority queue is implemented by using an array. Draw the priority queue
