Deletion Algorithm for dequeue

Step 1: [check for underflow]
  If front = 0 and rear = 0
  Output "underflow" and return

Step 2: [delete element at front end]
  If front > 0
  Value = q [front]
  Return [value]

Step 3: [check queue for empty]
  If front = rear
  Front = rear = 0
  Else
  Front = front +1

Step 4: [delete element at the rear end]
  If rear > 0
  Value = Q [rear]
  Return (rear)

Step 5: [check queue for empty]
  If front = rear
  Front = rear = 0
  Else
  Rear = rear - 1

Step 6:  Return
