Example of FizzBuzz

fizzbuzz.rb

# Write a program that prints out the numbers 1 to 100 (inclusive).
# If the number is divisible by 3, print Fizz instead of the number. 
# If it's divisible by 5, print Buzz. If it's divisible by both 3 and 5, print FizzBuzz.

# Final Version
puts (1..100).collect{ |i| (i % 3 == 0 && i % 5 == 0) ? "FizzBuzz" : (i % 5 == 0) ? "Buzz" : (i % 3 == 0) ? "Fizz" : i}.join("\n")

# Version 1
1.upto(100) do |i|
  if i % 3 == 0 && i % 5 == 0
    puts "FizzBuzz"
  elsif i % 5 == 0
    puts "Buzz"
  elsif i % 3 == 0
    puts "Fizz"
  else
    puts i
  end
end

# Version 2
(1..100).each do |i|
  puts (i % 3 == 0 && i % 5 == 0) ? "FizzBuzz" : (i % 5 == 0) ? "Buzz" : (i % 3 == 0) ? "Fizz" : i
end
