You may refer to the Floating Front Design algorithm (discussed in Queue and in code) for this problem where both front and back are array indices from 0 to array.size()-1. Q is an initially empty circular array-based QUEUE of size 8. After each statement on left has been evaluated, please enter the resulting values of the front and back on right (HINT: please refrain from guessing based on intuition and, instead, reference code in your Queue lecture for insight):

ArrayQueue Q = new ArrayQueue (8);       front =  ; back = 

Q.enqueue("P");                      front =  ; back = 

char x = Q.dequeue();                front =  ; back = 

Q.enqueue("C");                      front =  ; back = 

Q.enqueue("c");                      front =  ; back = 

Q.enqueue("C");                      front =  ; back = 

Q.peek();                            front =  ; back = 

Q.dequeue();                         front =  ; back =
