Implement a class Person.

Implement a class Teacher that extends Person.

class Person 
{
  protected String Surname, Name;
  protected int Age;
  Person(String Surname, String Name, int Age) // Constructor
  public String toString() // Print Surname Name Age
}

class Teacher extends Person 
{
  protected String Subject;
  protected int Salary;
  Teacher(String Surname, String Name, int Age, String Subject, int Salary) // Constructor
  Teacher(Teacher a) // Copy Constructor
  public String toString() // Print Surname Name Age Subject Salary
}

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 getOldestTeacher() // Return the Oldest Teacher
  public Teacher getOldestTeacher(String Subject) // Return the Oldest Teacher who runs the subject Subject
  public Teacher getYoungestTeacher() // Return the Youngest Teacher
  public Teacher getYoungestTeacher(String Subject) // Return the Youngest Teacher who runs the subject Subject
}

• the Oldest Teacher
• the Oldest Teacher who runs Physics
• the Youngest Teacher
• the Youngest Teacher who runs Math

System.out.println(list.getOldestTeacher());
System.out.println(list.getOldestTeacher("Physics"));
System.out.println(list.getYoungestTeacher());
System.out.println(list.getYoungestTeacher("Math"));

Input

Each line contains one of two types of people in the next format:

• PersonSurname Name Age
• TeacherSurname Name Age Subject Salary
