fizbuzz - a simple coding challenge

[altenbach]

Did all this somehow turn into a Rube Goldberg competition? 😄

[ThiCop]

For me: yes 🙂

How about a one line regular expression someone?

Hmmm...

I don't know if it's possible with one line, but I had to try this puzzle using regex,

Here's two ideas for a Rube Goldberg version of fizzbuzz... 😄

1) A VI that, for every integer n, run queries on Wolfram Alpha to check whether n is divisible by 3 and 5. Use the true or false responses to build your list of fizzes and buzzes. Remember to put in a nice long delay in your loop to avoid being blacklisted for denial of service...

2) Add the digits of the integer n together, and check whether the sum is divisible by three. Check the last digit to see whether it's 0 or 5, and proceed. You could be lazy and use Q&R to check the divisibility of the sum, but why stop there? This is supposed to be a Rube, goddamnit!

Actually, thinking about it, using the second allows you to test huge numbers:

Pardon the ressurection, but I just read this thread and had to claim the least number of functions. Would have been less if I didn't have to stop at 100.

Resurrecting the thread after exactly six years with a Python/regex solution:

import re

for i in range(1,101):
    out = ''
    if(re.search('^(0|1(01*0)*1)*$', bin(i)[2:])): out = 'FIZZ'
    if(re.search('[0-9]?[05]$', str(i))) : out += 'BUZZ'
    if(out == ''): out = str(i)
    print(out)

That source is flawed 😋.

Requirements clearly state to output "Fizz", "Buzz" and "FizzBuzz". Not "FIZZ", "BUZZ" and "FIZZBUZZ":

Write a program that prints the numbers from 1 to 100. 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".

So basically this ancient thread went full circle, because that's what started it all. Except that you now do a lot of string manipulations that you throw away in most cases a nanosecond later. So why do them unless needed? Also note that there is an "empty string?" primitive.

Compare that to the simplicity of e.g. my version.
