Q8. Consider the Stack ADT implemented using a Python list (called items) such that push() and pop() are defined as follows: def push(self, item): self.items.insert(0, item) def pop(self): return self.items.pop(0) What is the big-O complexity of push() and pop()? (A) both push() and pop() are O(n) (B) pop() is O(1) but push() is O(n) (C) push() is O(1) but pop() is O(n) (D) both push0 and pop() are O(n)

Q8. Consider the Stack ADT implemented using a Python list (called items) such that push() and
pop() are defined as follows:
def push(self, item):
self.items.insert(0, item)
def pop(sell):
return self.items.pop(0)
What is the big-O complexity of push() and pop()?
(A) both push() and pop() are O(n)
(B) pop() is O(1) but push() is O(n)
(C) push() is O(1) but pop() is O(n)
(D) both push() and pop() are O(n)
