. Repeat this process until a valid node is deleted. Returns null if the queue has not been deleted successfully after traversing. The following figure is a successful deletion of the structure diagram: from the above figure, we can see that, during the delete operation, the head over the number of nodes reached the threshold, triggering the executive head of the update, so that it points to the C node. After removing the header node from above, the two schematic diagram shows that the queue
