Recall that unlike Options where multiple errors are simply subsumed by a None, when we deal with multiple errors in Eithers, all but one are lost. Implement a datatype to return back multiple errors. Pay close attention to situations which do and do not require recording of multiple errors. You may use the following definition for the purpose of defining your data type. trait Partial[+A,+B] case class Errors[+A](get: Seq[A]) extends Partial[A,Nothing] case class Success[+B](get: B) extends Partial[Nothing,B] Now, implement the following functions for this datatype, accumulating errors when meaningful to do so: a) map b) flatMap c)] getOrElse d) orElse e) map2 f) traverse Finally: g) Implement the Try function to convert a possible exception into a Partial
Overload all relational operators (<, >, <=, >=, ==, and !=) for Box class. The boxes must be compared based on their volumes. The output should be the same as from the last assignment but now you must use overloaded operator functions instead of the normal member functions to accomplish your task. A sample output is given below: There are 4 Boxes in this program. Box 1 dimensions: length = 5'-3", width = 2'-7.5", height = 3'-8" and volume = 50.53 Box 2 dimensions: length = 4'-6", width = 9'-3", height = 2'-4" and volume = 97.12 Box 3 dimensions: length = 4'-6", width = 9'-3", height = 2'-4" and volume = 97.12 Box 4 dimensions: length = 3'-3", width = 9'-3", height = 2'-4" and volume = 70.14 Box 2 and Box 3 are equal. The largest box has dimensions: length = 4'-6", width = 9'-3", height = 2'-4" and volume = 97.12 The smallest box has dimensions: length = 5'-3", width = 2'-7.5", height = 3'-8" and volume = 50.53 by using c++

Assume the movie theater has the seatingarrangement of 10 rows x 20 seats, as illustrated to the below.The purpose is to design and write a seat assignmentprogram to maximize both customer satisfaction and customersafety. For the purpose of public safety, assume that a buffer of three seats inbetween Input DescriptionYou will be given a file that contains one line of input for eachreservation request. The order of the lines in the file reflects the order inwhich the reservation requests were received. Each line in the file will becomprised of a reservation identifier, followed by a space, and then thenumber of seats requested. The reservation identifier will have theformat: R####.

Design and implement an EuropeanOption class (with fixed strike priceK). It should hold information such as option type (call or put), spot price (of the underlying asset),strike price, interest rate, volatility (of the underlying asset) and time to maturity. Constructorsdon’t accept illegal values. Implement a getPrice() function which gives the price of the optionusing path independent simulation of the stock prices.Using the following dynamics for the stock price with the constant values:dSt= rStdt + σStdWtS0= 100K = 105r = 0.02σ = 0.05T = 10Add more features to the class defined in Problem 1, it should containfour member functions to compute the numerical Greeks (getDelta() for spot price, getRho() forinterest rate, getVega() for volatility, and getTheta() for time to maturity) of a given option.
Explain properly When we change (you can think of this as "dialing up" or "dialing down") the classification threshold for a binary classifier, which of the following happens? A. It affects the classification of some instances from False Positive to False Negative (and vice versa). B. It affects the classification of some instances from True Positive to True Negative (and vice versa). C. It affects the classification of some instances from False Negatives to True Positives (and vice versa). D. All of the above
The book makes the claim that "All built-in data types ... are ADTs". Think specifically about primitive data types (int, char, double, etc.): Do you agree or disagree? If you agree, explain why built-in data types fulfill the definition of an ADT. (Be sure to refer to at least one specific example.) If you disagree, explain why (give an example of a built-in type and why it doesn't meet the criteria for an ADT). (To be clear: "built-in" means part of the language specification and often given special recognition by the compiler. Classes that are part of a language's library -- such as ArrayList in Java -- aren't considered "built-in".)
This lab will exercise your understanding of some of the concepts covered in Chapter 13:overloading operators 1. Create a class, name of your choice, to represent a college class in which students might register. a. Create three private member variables:Class Name (to hold values such as CSC210)Number of StudentsClass Hours b. Overload the >> operator to input, from cin, into the class object, the Class Name and Class Hours c. Overload the << operator to output all the private member variables d. Overload the + (plus) operator to add a value to the Number of Students private member variable.This will represent students registering for the class. e. Overload the - (minus) operator to subtract a value from the Number of Studentsprivate member variable. This will represent students dropping the class. f. The default constructor should initialize the private member variables appropriately. 2. Write a client program to: a. Upon program execution, create one class object that…
Define the function print_trophic_class_summary(tli3_values) that accepts a list of trophic level index values and prints a summary outlining the number of lakes in each trophic classification, in order from highest trophic classification to lowest. See the examples for the required format. Notes: Your function must print the summary, not return it. In each state line, the initial number should be formatted with width 3. (Hint: :3 will be helpful) All possible states must be included in the output, even states with zero lakes. The following list will be helpful: ['Hypertrophic', 'Supertrophic', 'Eutrophic', 'Mesotrophic', 'Oligotrophic', 'Microtrophic', 'Ultra-microtrophic'] You must include and use one of your number_in_trophic_class functions (take your pick!), plus your trophic_class function. Basically, you can start with your answer to Question 5 or 6 and add your print_trophic_class_summary function definition after your previous definitions. For example: Test Result…

Use the aggregation (composition) concept to define and implement the class line(p1.x, p1.y, p2.x, p2.y) by using two points variables P1, and P2 of type point2D class defined in Q1. Beside the two points P1 and P2, the line class has the following functions: print(), MoveRel(Dx,Dy) (use the point2D’s MoveRel(Dx,Dy) function of the two points to achieve that), line(), line(x1,y1,x2,y2), line(P2D1,P2D2). * Your answer
