class ListOfPeople
{
ArrayList<Person> a = new ArrayList<Person>();
public void add(Person p) // Add person p to array list
public int size() // Return size of array list
public String toString() // Print people in array list. Each person print in a separate line
public Teacher getTeacherWithMaxSalary() // Return Teacher with maximum Salary

public Teacher getTeacherWithMinSalary() // Return Teacher with minimum Salary
public Teacher getTeacherWithMinSalary(String Subject) // Return Teacher with minimum Salary who runs the subject Subject
}
List of people will be created:
ListOfPeople list = new ListOfPeople();
Input data will be added to the list. Then next information will be printed:
- Teacher with maximum Salary
- Teacher with maximum Salary who runs Physics
- Teacher with minimum Salary
- Teacher with minimum Salary who runs Maths
System.out.println(list.getTeacherWithMaxSalary());
System.out.println(list.getTeacherWithMaxSalary("Physics"));
System.out.println(list.getTeacherWithMinSalary());
System.out.println(list.getTeacherWithMinSalary("Math"));
