Algorithm to Delete an Element from a Circular Queue.

Assuming that the Circular queue is stored in as array QU with size N.

This algorithm will delete an element from the circular queue and assign it to D-ITEM.

[Checking if QU is already empty or not?]
1. if FRONT = NULL then
{ 
write "Underflow !!"
return
}
else
{
2. set D_ITEM = QU [FRONT]
[Now Making FRONT point to the next element in the queue]
3. if FRONT = REAR then
{
FRONT = NULL
REAR = NULL
}
4. else if FRONT = N then
FRONT = 1
else
5. FRONT = FRONT + 1
6. return
