Question
6. Suppose a circular queue of capacity (n – 1)
elements is implemented with an array of n
elements. Assume that the insertion and
deletion operation are carried out using
REAR and FRONT as array index variables,
respectively. Initially, REAR = FRONT = 0.
The conditions to detect queue full and
queue empty are:
Full: (REAR+1) mod n ==
empty: (FRONT+1) mod n == REAR
FRONT,
Full: (REAR+1) mod n == FRONT,
empty: REAR == FRONT
Full: (FRONT+1) mod n == REAR,
empty: REAR == FRONT
Full: REAR == FRONT, empty:
(REAR+1) mod n == FRONT
