Answer:
Another way to block all inbound packets is to use the firewall layer of the circuit.
Explanation:
The firewall circuit layer is a firewall containing a table with four fields, mainly such as source port, destination port, source IP address, and destination IP address.
They are containing mainly the addresses or the ports that need to be blocked.
So we want to block all inbound packets, and also set the source port to 23 while the rest is set to zero, meaning that all inbound packets are blocked.

Answer:
The Python code with the function is given below. Testing and output gives the results of certain chosen parameters for the program
Explanation:
def first_last(seq):
if(len(seq) == 0):
return ()
elif(len(seq) == 1):
return (seq[0],)
else:
return (seq[0], seq[len(seq)-1])
#Testing
print(first_last([]))
print(first_last([1]))
print(first_last([1,2,3,4,5]))
# Output
( )
( 1 , )
( 1 , 5 )
Answer:
Yes it is possible for the following cases:-
- When the queue is full.
- When the queue is empty.
Explanation:
When the queue is full the the front and the rear references in the circular array implementation are equal because after inserting an element in the queue we increase the rear pointer.So when inserting the last element the rear pointer will be increased and it will become equal to front pointer.
When the queue is empty the front and rear pointer are equal.We remove an element from queue by deleting the element at front pointer decreasing the front pointer when there is only one element and we are deleting that element front and rear pointer will become equal after deleting that element.
