Answer:
To implement a move_to_rear function in Python, you can use the push, front, and pop functions to add and remove elements from the queue. Here is an example of how you could implement the move_to_rear function:
def move_to_rear(queue):
# Use the front() function to get the element at the front of the queue
front_element = queue.front()
# Use the pop() function to remove the element from the front of the queue
queue.pop()
# Use the push() function to add the element to the rear of the queue
queue.push(front_element)
This function takes a queue as an input, and uses the front, pop, and push functions to move the element at the front of the queue to the rear of the queue.
Here is an example of how you could use the move_to_rear function:
# Create a queue
queue = Queue()
# Add some elements to the queue
queue.push(1)
queue.push(2)
queue.push(3)
# Move the element at the front of the queue to the rear of the queue
move_to_rear(queue)
# Print the queue to verify that the element has been moved
print(queue) # Output: Queue(2, 3, 1)
In this example, the queue initially contains the elements 1, 2, and 3. The move_to_rear function is called with the queue as the input, which moves the element at the front of the queue (the element 1) to the rear of the queue. After the move_to_rear function is called, the queue contains the elements 2, 3, and 1, in that order.
