. a) Trace the following code segment, show the contents of the stack after each iteration of the for loop and the resulting stack:

values = Stack()

for i in range( 16 ) :

if i % 3 == 0 :

values.push( i )

elif i % 4 == 0 :

values.pop()

Trace the following code, show the contents of the queue after each iteration of the for loop and the resulting queue:

values = Queue()

for i in range( 16 ) :

if i % 3 == 0 :

values.enqueue( i )

elif i % 4 == 0 :

values.dequeue()

This is Python.

Thanks!
