A queue is implemented using an array of size $6$ with two indices $\verb|front|$ and $\verb|rear|$.

Initially, $\verb|front = rear = -1|$.

The following operations are performed in order:

ENQUEUE(10)
ENQUEUE(20)
ENQUEUE(30)
DEQUEUE()
ENQUEUE(40)
ENQUEUE(50)
DEQUEUE()
ENQUEUE(60)


Assume queue is simple linear queue


Which of the following options is correct?

  1. $\verb|front = 2|$, $\verb|rear = 5|$, Queue elements: $30, 40, 50, 60$
     
  2. $\verb|front = 1|$, $\verb|rear = 4|$, Queue elements: $20,30,40,50$
     
  3. $\verb|front = 2|$, $\verb|rear = 4|$, Queue elements: $30,40,50$
     
  4. $\verb|front = 3|$, $\verb|rear = 5|$, Queue elements: $40,50,60$
