Which of the following is the correct postfix representation of 22 - 6 + 33 / 4?

Which of the following postfix expressions evaluates to 15 using a stack?

How many times

does the "Hello" print?

node = Node(1)

node.next = Node(2)

node.next.next =

Node(3)

probe = node

while probe is not

None:

    print("Hello")

    probe = probe.next

What is the output

of the following code snippet?

class Node:

    def __init__(self, data):

        self.data = data

        self.next = None

head = Node(10)

head.next = Node(20)

head.next.next =

Node(30)

curr = head

while curr.next:

    curr = curr.next

print(curr.data)

What is the

postfix equivalent of the infix expression: (A + B) * C?

 If you have a chain A -> B -> C and you execute A.next = B.next

, what is

the result?

If you push 10, 20, 30 and then pop

once, what does peek return?

 What does this

snippet effectively do to the linked list?

# Assume head -> A

-> B -> C

if head and head.next:

    head.next = head.next.next
