More Queues The given diagrams show two more implementations of a queue, using arrays. The first queue Q1 always has its Head at position one of the array, and on ExitQ all values are moved up. The second queue Q2 moves “snake wise” down the queue (like the circular queue), but when the Rear hits the bottom of the array, then all entries are shifted up so that the Front is at the top again. Create programs to Enter and Exit these queues. Compare the two queue implementations briefly
