Question

Please do not give solution in image formate thanku. 

Provide the structure of a dynamic array-
based queue after each iteration of the for
loop when the following lines of code are
executed. You must list the queue's contents,
size, and capacity in the format provided
below. You should assume the initial capacity
is 2. If size == capacity before inserting a new
element, you will need to resize by doubling
the capacity and copying elements over to the
new memory location. Note that this queue
does NOT use a circular buffer
implementation.
values = Queue()
for i in range(16):
if i % 3 == 0:
values.enqueue(i)
elif i % 4 == 0:
values.dequeue()
Use the following format in the box below:
i = , values = [], size=, capacity=
(An example, not the right answer: i = 0,
values = [23], size = 1, capacity 1)
