Write a program that examines two numbers and exchanges their position using only the else clause
def countdown(n):
if n <= 0:
print('Blastoff!')
else:
print(n)
countdown(n-1)
Write a new recursive function countup that expects a negative argument and counts “up” from that number. Output from running the function should look something like this:
>>> countup(-3)
-3
-2
-1
Blastoff!
Write a Python program that gets a number using keyboard input. (Remember to use input for Python 3 but raw_input for Python 2.)
If the number is positive, the program should call countdown. If the number is negative, the program should call countup. Choose for yourself which function to call (countdown or countup) for input of zero.
Provide the following.
The code of your program.
Output for the following input: a positive number, a negative number, and zero.
An explanation of your choice for what to call for input of zero.
2. Write your own unique Python program that has a runtime error.
Create a class "House", with an attribute "area", a constructor that sets its value and a method
"ShowData" to display "I am a house, my area is 200 m2" (instead of 200, it will show the real
surface). Include getters an setters for the area, too.
• The "House" will contain a door. Each door will have an attribute "color" (a string), and a method
"ShowData" wich will display "I am a door, my color is brown" (or whatever color it really is).
Include a getter and a setter. Also, create a "GetDoor" in the house.
• A "SmallApartment" is a subclass of House, with a preset area of 50 m2.
• Also create a class Person, with a name (string). Each person will have a house. The method
"ShowData" for a person will display his/her name, show the data of his/her house and the data
of the door of that house.

Q#2: Write code (Print Statement) that generates the following SMS: Murali

peak time charge is applicable on this booking.
Create a Java program that simply outputs the text "Hello World" when you run it. Call your main class
"Application". In the same file as your main "Application" class, define a new class called "Person". You
don't need to put anything in the class. Now, right below where you output "Hello World" in your main
method, create an object from that (Person) class. Modify your "Person" class to add a constructor.
Make the constructor output the text "Constructor running!". Add another constructor in addition to
the constructor it's already got. Make this second constructor accept a parameter called name of type
String. Make this second constructor print the name parameter using System.out.println(). Finally,
change your "main" method, create two objects of Person class and call both constructors.
