- Assume that stack and queue are MyStack and MyQueue objects, respectively. WhT are the contents of stack and queue after the execution of the following code fragment.In the following code, assume myStack is a stack that holds integers. What would be the contents of the stack after the following operations, indicating what element is currently at the top and the bottom of the stack. myStack.push(1);myStack.push(2);myStack.push(3);myStack.pop();myStack.push(4);myStack.push(5);myStack.pop(); Group of answer choices 4 <- Top21 <- Bottom 5 <- Top31 <- Bottom 4 <- Top32 <- Bottom 5 <- Top21 <- Bottom4. a) Using the stack diagram, convert the following infix expression to a postfix expression. A + B / C * (D – E) b) Referring to question 4 (a), give the value of postfix expression by using the stack concept if provided: A=13, B=20, C=4, D=30, E=25
- struct Faculty { int id; char name[30]; char status[10]; //status permanent or visiting Faculty next; }; Assume we have three stacks S, V and P. S is a stack having mix data of visiting and permanent faculty members, V is empty and for visiting faculty memebrs and P is also empty for permanent faculty members. Using primitive functions of stack write a C++ code which reads entire data from S and write on respective stack V or P.Q3: Write the C++ code of Stack which is performed multiple task which are given below and performed all task by using Arrays. Push values 10, 20, 5 , 50, 40, 60, 45 Pop values 45, 60, and 40 Sort all values in Stack Please create is empty and stack function for telling them stack is empty or full.Q3: Write the C++ code of Stack which is performed multiple task which are given below and performed all task by using Arrays. Push values 10, 20, 5 , 50, 40, 60, 45 Pop values 45, 60, and 40 Sort all values in Stack Please create is empty and stack function for telling them stack is empty or full.NOTE: PLEASE SOLVE THE QUESTION PROPERLY AND ACCORDING TO THE REUIRED THINGS.
- Solve the code much needed. Given a stack, a function is_consecutive takes a stack as a parameter and thatreturns whether or not the stack contains a sequence of consecutive integersstarting from the bottom of the stack (returning true if it does, returningfalse if it does not). For example:bottom [3, 4, 5, 6, 7] topThen the call of is_consecutive(s) should return true.bottom [3, 4, 6, 7] topThen the call of is_consecutive(s) should return false.bottom [3, 2, 1] topThe function should return false due to reverse order. Note: There are 2 solutions:first_is_consecutive: it uses a single stack as auxiliary storagesecond_is_consecutive: it uses a single queue as auxiliary storage"""import collections def first_is_consecutive(stack): storage_stack = [] for i in range(len(stack)): first_value = stack.pop() if len(stack) == 0: # Case odd number of values in stack return True second_value = stack.pop() if first_value - second_value != 1: # Not…Select true or false for the statements below. Explain your answers if you like to receive partial credit 4) Given a stack implemented as a standard linked list (only a head pointer) with O(1)push and O(1) pop, and the following functions are performed in sequence:Push(“Charmander”), Push(“Squirtle”), Push(“Bulbasaur”), Pop(), Push(“Larvitar”),Push(“Eevee”), Pop(), Pop()Which of the following is true after all the functions are executed?a. Charmander and Squirtle will be the only elements left on the stackb. The head node will be pointing to Charmanderc. If you Push(“Pikachu”), it will be the last node of the linked list1. a) Using the stack diagram, convert the following infix expression to a postfix expression. A* (B – C + D) – E / F b) Referring to question 1 (a), give the value of postfix expression by using the stack concept if provided: A=2, B=3, C=8, D=10, E=10 and F=2
- question 1 Write a program to evaluate a postfix expression. Input: a postfix expression. E.g. 3 5 + Output: the result of the expression. E.g. the result for the above input is 8. Note: You must use the stack to implement this task. And please give the stack solutions for both the following implementations: Implement the array-based stack Implement the pointer-based stack Test your program using the following expressions: 3 5 + 3 5 + 6 * 3 5 6 + * 3 5 6 * 8 - 2 / + 12 20 + 16 / do not copy from chegg and do in c++Question#3.Write a Python program to reverse a stack using recursion. Problem Solution Hints: 1. Create a class Stack with instance variable items initialized to an empty list. 2. Define methods push, pop, is_empty and display inside the class Stack. 3. The method push appends data to items. 4. The method pop pops the first element in items. 5. The method is_empty returns True only if items is empty. 6. The method display prints the elements of the stack from top to bottom. 7. Define function insert_at_bottom which takes a stack and a data item as arguments. 8. The function insert_at_bottom adds the data item to the bottom of the stack using recursion. 9. Define function reverse_stack which takes a stack as argument. 10. The function reverse_stack reverses the stack using recursion. 11. Create an instance of Stack, push data to it and reverse the stack.Use a stack to reverse the input integer values. Check the stack grows as more elements are pushed. Use with and without function pointer in each of the problem (Please give correct answer with explanation)
