Answer to Question #325865 in C# for Anji

Question

In a university, there is a certain system of credits. Each of student is given a ‘credit limit’ which specifies the maximum credits of a subject they can take. A student can take any number of subjects which are under his/her credit limit.

There are N students and K subjects.Each subject has a specified number of credits .when student choose a subject ,it becomes a (student,subject)pair.

Find the maximum number of possible(subject,student)pairs for the given credit limits and subject credit requirements.

Input1:K denoting the number of subjects

Input2:An array of K elements each denoting the credits to take a subject

Input3:N denoting the number of students

Input4:An array of N elements each denoting the credit limit of a student.

Output:Your should return the maximumnumber of possible required pairs.

Example1:

Inpput1:3

Input2:{44,45,56,39,2,6,17,75}

Input3:1

Input4:{54}

Output:6

Answer 1

        public int CreditLimit { get; set; }
        public Student(int limit)

            CreditLimit = limit;
        }

    class Subject
    {
        public int MaximumCredits { get; set; }
        public Subject(int limit)
        {
            MaximumCredits = limit;

    }
    static void Main()

        Console.Write("Enter the number of subject: ");
        int n =  int.Parse(Console.ReadLine());

        Console.ReadKey();

                    maxCount++;
            }
            Console.WriteLine($"For the {i + 1} student, the maximum number of subjects is {maxCount}");
