Suppose we want to make a 10 item queue starting from location x4000. in class, we discussed using a head and a tail pointer to keep track of the beginning and end of the queue. in fact, we suggested that the head pointer could point to the first element that we would remove from the queue and the tail pointer could point the last element that we have added the queue. it turns out that our suggestion does not work. part a) what is wrong with our suggestion? (hint: how do we check if the queue is full? how do we check if it is empty? )part b) what simple change could be made to our queue to resolve this problem? part c) using your correction, write a few instructions that check if the queue is full. use r3 for the head pointer and r4 for the tail pointer. part d) using your correction, write a few instructions that check if the queue is empty. again, using r3 for the head pointer and r4 for the tail pointer.
