Is that how you would solve it in your job interview? Just curious.

I’ve got this in 67 characters…

Actually, I’ve now got 65 character or 62 characters. The 62
character version interprets the specification literally by
printing “Fizz”, “Buzz” or “FizzBuzz” with the double
quotation marks :slight_smile:

Speaking of literal interpetation, the original Quiz post came across in
my mail with a number of non-standard ASCII characters wrapped around
the Fizz and Buzz text.

  but for multiples of three print “Fizz” instead of the

number and for the multiples of five print “Buzz”. For
numbers which are multiples of both three and five
print “FizzBuzz”.

I spent a bunch of time trying to figure out how to output those
(unsuccessfully) after getting my initial solution working. Based on a
number of the other posts on the topic it appears that the real
requirement was to output Fizz, Buzz or FizzBuzz only without the other
characters. Is that correct?

Just curious while I wait to post my first quiz submission.

I’ll match your 62, but I’m still thinking that some clever tricks might
get it lower!

I got to reach 56 bytes, but I highly doubt I can shave one more byte

it.

Yes. Probably this symbols came from non-standard quotation marks.

I can’t wait for tomorrow to see how you all got such ridiculously low
numbers =)

We failed, just look at the achieves, I do not consider that a spoiler
because I am sure James was aware of the Ruby ML community’s attempt
to get it to 56 bytes in March if I recall correctly.

And no I guess nobody would golf at a job interview unless it were for
the PGA of course.

I know at an interview I would start with (well not exactly, but this
makes checking golf results easier)…

I’ve got 60 now. But it sounds like the magic target is 56 :frowning:

What you create above is an array with an element that is a range, so:

irb(main):001:0> array = []
=> []
irb(main):002:1> array << (1…100) #you don’t need 'array = ’ in front
of this
=> [1…100]
irb(main):003:2> array
=> [1…100]
irb(main):004:0> array.class
=> Array
irb(main):005:0> array[0].class
=> Range
irb(main):006:0> array << “blah”
=> [1…100, “blah”]

I’m guessing you want an array created from a range? If so, one way
would be:

irb(main):007:0> array = (1…10).to_a
=> [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

Also, some range methods return an array (like (1…100).map {} for
example).

Also, i seem to be unable to put a range into an array. Yes, i
understand this is very simple, but when I did what I THOUGHT would
work, I can’t get a range of numbers to be inserted into an array.
Apparently this does not work:
array = []
array = array << (1…100)

array = (1…100).to_a

or

array = [*1…100]

or (golfers favorite?)

array = *1…100

or (if you need to add it to existing array):

array.push *1…100

Alrighty - looks good so far. When would it be appropriate to use ‘and’?

Extra bonus fun question: If gsub! doesn’t work for integers, what

Don’t forget these:

?d

is the same as 100 and save a character

puts :Fizz

will print Fizz, just as well as :Fizz and saves a character, and if
you really want to save a couple chars figure out how to only have the
Fizz and Buzz literals and combine them in the multiple of 15 space.

All that having been said, my solution (not golfed) will include
something like:

module Enumerable
def map_every(n)
m = n - 1
result = []

self.each_with_index do |elem,i|
  if i % n == m
    result << yield(elem,i)
  else
    result << elem
  end
end

result

end
end

not quite

A non-golf solution of mine :

for n in (1…100)
if n%3==0 && n%5==0
puts “FizzBuzz”
elsif n%3==0
puts “Fizz”
elsif n%5==0
puts “Buzz”
else
puts n
end
end

Does above code fit for a job interview? :slight_smile:

Darn, just wanted to write that I got a 58 one here. We had that in
#ruby-lang once too and golfed about it a bit. IIRC we had a smaller one
than 58 (didn’t store it back then), but I don’t remember how small. If
somebody knows blinks e-mail…
