| The normal way: | |
| def fizzbuzz(first, last) | |
| first.upto(last) do |i| | |
| if dividesby?(i,3) && dividesby?(i,5) | |
| puts "FizzBuzz" | |
| elsif dividesby?(i,3) | |
| puts "Fizz" | |
| elsif dividesby?(i,5) | |
| puts "Buzz" | |
| else | |
| puts i | |
| end | |
| end | |
| end | |
| # fizzbuzz(1, 100) | |
| # Or we can do it like this: | |
| =end | |
| def divides_by?(dividend, divisor) | |
| dividend % divisor == 0 | |
| end | |
| def fizzbuzz(first=1, last=100, fizz_value=3, fizz_string="Fizz", buzz_value=5, buzz_string="Buzz") | |
| # I used #map so that we can save the transformed array in a variable if we want. | |
| (first..last).map do |x| | |
| fizz = fizz_string if divides_by?(x, fizz_value) | |
| buzz = buzz_string if divides_by?(x, buzz_value) | |
| # (recall that, in Ruby, nil is falsey and strings are truthy) | |
| (fizz || buzz) ? [fizz, buzz].join : x | |
| end | |
| end | |
| # I took the puts out of the method so printing all those lines is intentional, not a side effect. | |
| puts fizzbuzz | |
| # fizzbuzz(12, 60, 4, "Vladimir ", 6, "Putin") |
