# Write a program that outputs the string representation of numbers
|
|
# from 1 to n. But for multiples of three it should output “Fizz”
|
|
# instead of the number and for the multiples of five output “Buzz”.
|
|
# For numbers which are multiples of both three and five output
|
|
# “FizzBuzz”.

# Approach 1: Hash it!
