Write a main program to create a stack object of type Integer. Place 7 integers in this Stack. Create a Bag of Integer object and place 20 random integers in this Bag. The main program must print the value of each item in the Stack and display how many of that item is in the Bag. After these values are displayed both Stack and Bag objects must have their original values in them.

- Write a program that inputs a list of numbers already stored in a stack STACK and sorts them, making use of a temporary stack TEMP. The sorted list of numbers should be made available in STACK.Suppose you have a stack with a maximum size of 1000 elements and you want to perform the following operations: Push 500 elements onto the stack. Pop 200 elements from the stack. Push 800 elements onto the stack. Pop all remaining elements from the stack. What is the final size of the stack after performing all these operations?In C++, Write a program which is menudriven ( i) Push, ii) POP, iii) Peek iv) Print). It will create a stack ofinteger type data. You have to implement the following operations.a. Push (Insert a data to the stack)b. Pop (Print the data at the TOP and remove thedata)c. Peek (Print the data at the TOP)d. Print (Print the whole stack)

- A stack has following variables initialized, answer question 5 &6 using these values int size = 7; int top = —1; int [ ] arr = new int [size] ; Q5. What will be value of the top variable when the stack is empty? Q6. What will be value of the top variable when the stack is full?Write a structure to represent a Node in a singly linked-list-based stack similar to the onediscussed in class. Your stack will store integer values. Your program will read a series of integers(until the user enters a non-integer) and store them in a stack, then print them in the reverse order;You will write three functions to assist with this task: push, printStack, and deleteStack.The function push takes a number and a Node and adds the number to the head (top) of thestack by creating a new Node (using malloc) and returning a pointer to this Node. This new nodeis now the top of your stack.The function printStack will need to iterate through your stack and print each one (5 spacesper number, left-aligned), with a new line following the nal number. You will need a pointer thatyou update to the next Node each time you print one. Since you add new items to the top of thestack, the newest elements will be printed rst, giving the reverse-order behavior requested.The function deleteStack…I am writing a stack code, where there are two stacks that reads an array of 40 numbers and puts them in ascending and descending order. I put my code on the bottom. The requirements of the code was to write the stack functions using arrays, but whenever i run the code it does not work. However, if use stack in built function the code works. Help me please. PS: I Attached the code requirements. struct Stack1 { int *arr; int NextIndex; int capacity; Stack1() { capacity = 20; arr = new int[capacity]; NextIndex = 0; } int size () { return NextIndex; } bool isEmpty() { if (NextIndex == 0) { return true; } else return false; } void push(int ele) { if (NextIndex == capacity) { int *newArr = new int[2*capacity]; for(int i = 0; i < capacity; i++) {…
- A CapnStackSparrow is an extended stack that supports four main operations: the standard Stack operations push(x) and pop() and the following non-standard operations:• max(): returns the maximum value stored on the Stack.• ksum(k): returns the sum of the top k elements on the Stack.The zip file gives an implementation SlowSparrow that implements these operations so that push(x) and pop() each run in ?(1) time, but max() and ksum(k) run in ?(?) time. For this question, you should complete the implementation of FastSparrow that implements all four operations in ?(1) (amortized) time per operation. As part of your implementation, you may use any of the classes in the Java Collections Framework and you may use any of the source code provided with the Java version of the textbook. Don't forget to also implement the size() and iterator() methods. Think carefully about your solution before you start coding. Here are two hints:1. don't use any kind of SortedSet or SortedMap, these all require…Code in C One of the applications of a stack is to backtrack - that is, to retrace its steps. As an example, imagine we want to read a list of items, and each time we read a negative number we must backtrack and print the five numbers that come before the negative number and then discard the negative number. Use a stack to solve this problem. Use a stack and push them into the stack (without printing them) until a negative number is read. At this time, stop reading and pop five items from the stack and print them. If there are fewer than five items in the stack, print an error message and stop the program. After printing the five items, resume reading data and placing them in the stack. When the end of the file is detected, print the message and the items remaining in the stack. Sample Output 1 2 3 4 5 6 7 -1 7 6 5 4 3 9 6 4 3 -2 3 4 6 9 2 -3 Number of items left is less than five! Program is terminating! Project name : Backtrack Filenames: backtrack.h, backtrack.c,…A SpecialStackTM is a stack modified to support the following two operations: PUSHCLEAR(v) successively pops consecutive items from the top of the stack that are less than u, then pushes v onto the stack. POP() deletes the item at the top of the stack. Assume these operations are implemented using a singly-linked list. PUSHCLEAR(v) iter- ates through the linked list to pop the applicable items and then adds v to the beginning. POP() deletes the first item. (a) Describe the ordering of values on the stack. (b) Explain how a single call to PUSHCLEAR(V) could take (n) time. (c) If we assume that every operation takes linear time, we get a naive bound of O(n²) on the total runtime. But this doesn't consider the fact that these expensive operations happen infrequently so let's analyze it more closely. Show that any sequence of n operations takes O(n) time. -
