- We want to pull something from a stack. What pre-condition can be introduced in this scenario? Wrrite an expression for the Pre-Condition. Course: Formal Methods in Software EngineeringIN PYTHON, USING RECURSION: ask the user for the length of a square and the character they want to use. Draw the square. Once the user creates the square with their specification, ask them if they want it to be smaller or larger and how many times. Draw all the squares growing in size to the specified range. (the last solution someone gave me here did not work. Also please tryh to use a recursive queue.)Which of the following statements in the picture below can be applicable to dijkstra's algorithm but not prim's algorithm?
- Write a program in Python to show how a queue works using empty, size, front, back, push item onto queue, and push item off queue.Write a Queue implementation that uses a circular linked list, which is the sameas a linked list except that no links are null and the value of last.next is first whenever the list is not empty. Keep only one Node instance variableThe program inserts a number of values into a priority queue and then removes them. The priority queue treats a larger unsigned integer as a higher priority than a smaller value. The priority queue object keeps a count of the basic operations performed during its lifetime to date, and that count is available via an accessor. In one or two places I have put statements such as op_count++;, but these are incomplete. We only count operations involved in inserting and removing elements, not auxiliary operations such as is_empty() or size() The class implements a priority queue with an unsorted vector. Your assignment is to re-implement the priority queue implementation using a heap built on a vector, exactly as we discussed in class. Leave the framework and public method interfaces completely unchanged. My original test program must work with your new class. You will have to write new private methods bubble_up and percolate_down. You should not implement heapify or heapsort. #include…
- Student should be able to develop the programs for queue using arrays and linked list Exercise 1: Implementation of Queue using Array or Linked list Real life situation. Design a simulation that can help to answer it. Customers at a grocery store want to check-out The grocery have 3 counter and the costumer must choose one of the counter Counter 1:3 people assembly Counter 2: 2 people assembly Counter 3: 3 people assembly The costumer should choose the fastest way to check outWrite a program for Stack (Array-based or linked list-based) in Python. Test the scenario below with the implementation and with the reasoning of the answer. Make comments with a short description of what is implemented. Include source codes and screen-captured outputs. Stack: A letter means doing a push operation and an asterisk means doing a pop operation in the below sequence. Give the sequence of letters that are returned by the pop operations when this sequence of operations is performed on an initially empty stack. A*BCE**F*GH***I*The following are the operations that you can do using a single linked list. Choose only one operation then create the algorithm and simulate. The attached Rubric will be used in evaluating the activity. 1. Delete a particular node in a single linked list 2. Delete the first node of a single linked list 3. Insertion after a given node of a single linked list 4. Insertion at a given position in a single linked list 5. Insertion before a given node in a single linked list 6. Reverse a single linked list EX: Delete the last node of a single linked list Problem" Deletion of the last node in a single linked list Algorithm" Step 1: if HEAD = NULL Write UNDERFLOW Go to Step 8 Step 2: SET PTR = HEAD Step 3: Repeat Steps 4 and while PTR à NEXT = NULL Step 4: SET PREPPTR = PTR Step 5: SET PTR =PTR à NEXT [End of loop] Step 6: SET PREPTR à NEXT = NULL Step 7: FREE PTR Step 8: EXIT…
- Develop a static method that takes two queues of sorted items as arguments and returns a queue that results from merging the queues into sorted order.Your crazy boss has assigned you to write a linear array-based implementation of the IQueue interface for use in all the company's software. You've tried explaining why that's a bad idea with logic and math, but to no avail. So - suppress your inner turmoil and complete the add() and remove() methods of the AQueue class and identify the runtime order of each of your methods. /** A minimal queue interface */ public interface IQueue { /** Add element to the end of the queue */ public void add(E element); /** Remove and return element from the front of the queue * @returns fırst element * @throws NoSuchElementException if queue is empty */ public E remove(); /** Not an ideal Queue */ public class AQueue implements IQueue{ private El) array: private int rear; public AQueue(){ array = (E[)(new Object[10]): rear = 0: private void expandCapacity) { if (rear == array.length) { array = Arrays.copyOf(array, array.length 2): @Override public void add(E element) { / TODO @Override public E…PLEASE SEND ME FAST
