_B_
( _ indicates empty
slot in a Queue)
What will be contents of Queue after
Insert(D) operation?​

Answer 1

Answer:

To insert an element D into the circular queue, we need to increment the value of the rear pointer and add the element to that position.

Explanation:

To insert an element D into the circular queue, we need to increment the value of the rear pointer and add the element to that position. However, since the queue is circular, we need to wrap around to the beginning of the array if we reach the end.

Here's what the queue looks like initially:

front = 2, rear = 4

Queue = __, A, B, C, __, __

To insert the element D, we increment the rear pointer to 5 (wrapping around to the beginning of the array) and add D to that position:

So the final contents of the queue after the Insert(D) operation are A, B, C, __, D.
