- Machine organization The following operations are performed on a stack: PUSH A, PUSH B, POP, PUSH C, POP,POP,PUSH D, PUSH E, POP, PUSH F. What does the stack contain after each operation?54. What is the difference between the top and pop operations of a stack? Group of answer choices The top operation removes the top item of the stack. The pop operation returns a reference to the top item on the stack and remove it. The top operation removes the top item of the stack. The pop operation returns a reference to the top item on the stack without removing it. The pop operation removes the top item of the stack. The top operation returns a reference to the top item on the stack without removing it. The pop and top operations are doing the same thing which removes the top item of the stack. The pop operation removes the top item of the stack. The top operation returns a reference to the top item on the stack and remove it.Stack, Queue and Deque5.1. Understand the basic operations for Stack, Queue and DequeExample: Suppose that Queue q is implemented by a circular array data with the size 3. Please drawthe state of the Queue q and circular array data after each of the following steps.1) Queue q = new Queue();2) q.enqueue(5);3) q.enqueue (2);4) q.enqueue (9);
- Which operation of a stack removes and stores the top element of the stack.A stack has five nodes; the data of the nodes is given below: [top ] 6 -- 1 -- 9 -- 5 -- 7 [bottom ] After a pop function call, the stack is as follows: [top ] 1 -- 9 -- 5 -- 7 [bottom] What will the stack look like after a node is removed and then a node with the value 21 is added?If a resource in a stack cannot be created, what happens?
- 23. If a stack contained the entries 128, 90, 56, 341 (from top to bottom), what would be at the top of thestack after the statement push(106) is executed?What are the operations that can be performed on a stack?(Printing a Sentence in Reverse Order with a Stack) Write a program that inputs a line of text and uses a stack object to print the line reversed.
- Determine how the stack behaves when it is permitted to operate on its own.A stack is very useful in situations when data have to be stored and then retrieved in the —- order. A) same B) reverse C) ascending D) descendingGiven main.py, complete the Stack class in Stack.py by writing the push() and pop() methods. The stack uses an array of size 5 to store elements. The command Push followed by a positive number pushes the number onto the stack. The command Pop pops the top element from the stack. Entering -1 exits the program. Output "Can't push, stack is full" when push() is called on a full stack. Output "Can't pop, stack is empty" when pop() is called on an empty stack. Ex. If the input is: Push 1 Push 2 Push 3 Push 4 Push 5 Pop -1 Code given main.py(read-only) from Stack import Stack if __name__ == "__main__": stack = Stack(5) input_line = input() while input_line != '-1': split_input = input_line.split(' ') command = split_input[0] if command == 'Push': number_to_push = int(split_input[1]) stack.push(number_to_push) print('Stack contents (top to bottom):') stack.print_stack() elif command == "Pop":…
