- Scala programmingarrow_forwardHow do I code the following stack in C program?arrow_forward1. A company wants to evaluate employee records in order to lay off some workers on the basis of service time (the most recently hired employees are laid off first). Only the employee ids are stored in stack. Write a program using stack and implement the following functions: Main program should ask the appropriate option from the user, until user selects an option for exiting the program. Enter_company (emp_id)- the accepted employee id(integer) is pushed into stack. Exit_company ()- The recently joined employee will be laid off from the company Show employee ()- display all the employees working in the company. count()- displays the number of employees working in the company. i) ii) iii) iv)arrow_forward
- Source Booksh... m HBO Max AAP CS A Java Cours... Assume you have a stack, called myStack, implemented with single-linked nodes, that looks like this: 573 -> 408 -> 142 -> 886 'top' is a reference variable that points to the node containing 573, and 'count' is an internal int that holds the count of nodes (currently 4). The following code is ran: Integer firstPop = myStack.pop(); Integer secondPop = myStack.pop(); myStack.push(firstPop); myStack.push(760); myStack.push(secondPop); myStack.push(738); Select all of the following that are true at the end of this code. The variable secondPop refers to 142. O The element 760 is contained by the third node in this stack (where 'top' is considered the first node). O The count is currently equal to 6. The variable first Pop refers to 573. O The Integer held by firstPop is now the element contained by the node referenced through the top pointer. 886 is the only Integer that didn't change position in the LinkedStack. O The Integer held by second…arrow_forwardHow would you design a stack which, in addition to push and pop, also has a function min which returns the minimum element? Push, pop and min should all operate in O(1) time. Your design (in pseudo code) should include a class Stack and three functions, i.e., push, pop, and min.arrow_forwardUsing the PEP 8 machine. Create a function that takes 2 arguments and returns a result. When I say function I mean that the parameters and the return value are passed on the stack . You code must have a function and a main program that calls the function using the stack. Assignment will not be accepted if you are not passing parameters and return value in the stack. Please note a complete "pass by stack" example is below. The function adds two numbers. Feel free to use that as starter code. The function you do should be one of three operations: 1) multiply - return the product of the two factors 2) divide - return the quotient ( integer arithmetic ) 3) remainder / modulo - return the remainder of the division of the two factors.arrow_forward
- please send asm file and follow all the steps. I need a complete answer to study for final so little explanation would be helpful. Thank youarrow_forward: How would you design a stack which, in addition to push and pop, has a function min which returns the minimum element? Push, pop and min should all operate in 0(1) time.arrow_forwardConsider the following statements: stackType<int> stack; int x; Suppose that the input is: 14 53 34 32 13 5 -999 Show what is output by the following segment of code: cin >> x; while (x != -999) { if (x % 2 == 0) { if (!stack.isFullStack()) stack.push(x); } else cout << "x = " << x << endl; cin >> x; } cout << "Stack Elements: "; while (!stack.isEmptyStack()) { cout << " " << stack.top(); stack.pop(); } cout << endl;arrow_forward
- Create one program that lets the user enter multiple digits in base 10 and the program will display it in all basses From base (2) to Base (36).arrow_forwardSuppose that you want to create the following program: void copyStack(std::stack<int> &srcStack, std::stack<int> &dstStack); This operation copies the elements of srcStack in the same order onto dstStack. Consider the following statements: Int main() { Std::stack<int> stack1; Std::stack<int> stack2; … copyStack(stack1, stack2); The function copyStack(stack1, stack2); copies the elements of stack1 onto stack2 in the same order. That is, the top element of stack1 is the top element of stack2, and so on. The old contents of stack2 are destroyed and stack1 is unchanged. Note that std::stack<int> is a C++ standard library stack object type. Complete the following program void copyStack(std::stack<int> &srcStack, std::stack<int> &dstStack) { // check if srcStack is empty -> error message is printed and return // remove all the elements of dstStack // create a temporary stack tempStack for…arrow_forward
