What is the status of myqueue and myqueue2 after execution of following code?
my_queue1 = Queue(3)
my_queue2 = Queue(3)
for index in range (0, 3) :
my_queuel.enqueue(index *3)
for index in range(0, 3) :
if(index == 2) :
break
my_queue.enqueue(my_queue.dequeue())
my_queue2.enqueue(12)
# Assume Queue class and methods existsQuestion 9
Consider the below inputs:
input_linked_list(Head to Tail): 1->2->5->3
input_stack(Top to Bottom): 4,2,5,10
What will be the content of input_linked_list from head to tail and input_stack from top to bottom after the execution of the function genereate.
Assumption: Stack and LinkedList Classes, with the necessary methods, are available
def generate(input_linked_list): temp = input_linked_list.get_head() #get_head() returns the head node element = 0 while(temp.get_next() is not None): #get_next() returns the address of the next node temp.set_data(temp.get_data()+temp.get_next().get_data()+element) #get_data() returns the data stored in the node if temp.get_data()%2 != 0: temp.set_data(temp.get_data+input_stact.pop()) #set_data(data) updates the data stored in the node element = temp.get_data() else: input_stact.push(element) element = temp.get_next().get_data() temp = temp.get_next() temp.set_data(temp.get_data()+input_stact.pop())
