- suppose there is a class Roster. Roster has one variable, roster, which is a list of tuples containing the names of students and their numerical grades- for example, [('Richard',90), ('Belle',67), ('Christine',85), ('Francine',97)]. Roster has a function findValedictorian that returns the name of the student with the highest grade. Find the valedictorian of the Roster object englishClass and store it in the variable valedictorian.Using Python, create a program that has the following classes: Point - Just like in the lecture, with attributes x and y set to 0 by default. Circle - Contains two attributes, center and radius. center is of type Point defined above (initialize a Point instance for this), while radius is set to 0 by default. The program must have the function point_in_circle(c, p) where c is a Circle and p is a Point. The function returns True if the point is within the circle, and False otherwise. You may use the math module (and nothing else) if necessary. You may also create other functions that can help you code the main function much easier. Example usage # Initialize a circle with center at (0, 0) and radius 1 (unit circle). c = Circle() c.center.x, c.center.y, c.radius = 0, 0, 1 # Initialize a point located at (1, 1) p = Point() p.x, p.y = 1, 1 # This returns False since (1, 1) is outside the circle point_in_circle(c, p) hint: apply "classes" conceptWe have a parking office class for an object-oriented parking management system using java Add (implement )a function to the Parking Office class to return a collection of customer ids (getCustomerIds) using java I have attached two class diagrams with definitions of all related classes in our system (i.e car, customer, .....). N.B. Parking office methods in the class definition like register, getcustomer and addcharge have already been implemented, we just need an additional getcustomerID function as mentioned above Explain the code you wrote with a few words

The function should count the number of recursive calls. State its computational complexity using big-O notation, and justify your answer. The fib function header has been modified to include the counter as the second parameter. Define the Counter class, it should have three methods: __init__, increment, and __str__. When an instance of the Counterclass is passed as a parameter, the countproperty of that instance should be incremented based on the number of recursive calls. The __str__ method should return the countproperty's value as a string. Please can you change the solution to this problem here, because this is wrong. """ File: fib.py Project 11.7 Employs memoization to improve the efficiency of recursive Fibonacci. Counts the calls and displays the results.

Problem Part B Now, write another function with the interface simulateRandomWalk(nsim,nstep,startPosition) that simulates nsim number of random-walks, each of which contains nstep steps and starts at startPosition. Then, this function calls doRandomWalk() repeatedly for nsim times and finally returns a vector of size nsimcontaining final locations of all of the nsim simulated random-walks. Problem Part C Now write a script that plots the output of simulateRandomWalk() for nsimnstepstartPosition===1000010−10 The resulting plot should look like the following, How do you interpret this result? How can uniformly-distributed random final steps end up having a Gaussian bell-shape distribution.
- Can you implement the Derived Class Parameterized constructor? A solution is placed in the "solution" section to help you, but we would suggest you try to solve it on your own first. Implement the constructor Dell(String name) of the Derived Class Dell which takes a string, name. We have already implemented the Base Class Laptop with the member function getName() and a parameterized constructor. Input# Laptop name is being passed through the parameterized constructor. Output# getName() method is returing Laptop name. Sample Input# Dell dell = new Dell("Dell Inspiron"); Sample Output# "Dell Inspiron"Implement a “Library” class with attributes such as list of books, librarians, timings etc. • Implement functions to search, issue & report over due booksA(n)_ is a class that only contains virtual functions that are pure virtual. Fill in the blanks with your answer to this question.
- Class student inherits from superclass Person. Which assignment is legal? a) Student s = new Person(); b) Person p = new Student(); c) Student s = new Student(); d) Person p = new Person();I need help Implement class Contact :public Person. I provided person.h.Given two points in the plane (?,?) and (?,?), the slope of the line through them is the number ? given by?=?−? ?−?i.e. the difference in the y-coordinates divided by the difference in the x-coordinates, or rise/run. Recall the Point class defined in the series of examples found here. Below is a stripped down version of this class, with only the initializer (given), and two new class functions called slope(?,?) and colinear(?, ?, ?). The first returns the slope of the line through the points ? and ?. The second returns True if and only if the three points ?, ? and ? lie on a line.
