Exercise 2 - FizzBuzz

Write a program that prints all the numbers from 1 to 100, with two exceptions. For numbers divisible by 3, print "Fizz" instead of the number, and for numbers divisible by 5 (and not 3), print "Buzz" instead.

Exercise 3 - Modify FizzBuzz

Modify the FizzBuzz program to print "FizzBuzz" for numbers that are divisible by both 3 and 5 (and still print "Fizz" or "Buzz" for numbers divisible by 3 or 5, respectfully.)

Exercise 4 - Chessboard

Write a program that creates a string that represents an NN grid, using newline characters to separate lines. At each position of the grid there is either a space or a "#" character. The characters should form a chessboard. (Output should show something like the image below.) Prompt for a value so that the program works for any size, outputting a grid of the given width and height.
