This repository provides two different ways to calculate solutions for the classic FizzBuzz problem.
Call with a starting and ending number:
fizzbuzz 33, 77
One line will print a line to the console for each number in the range given, declaring whether that number is Fizzy, Buzzy, FizzBuzzful or just an ordinary number.
Note: the second number given as an argument to fizzbuzz() must
be larger than the first, as this implementation uses a range object
which evaluates to nil if that pattern is not followed.
A variable num_array is assigned by converting a range object (using the given arguments as endpoints) into an array. For each item in num_array an fresh output variable is assigned to an empty string. If the number isn't divisible by 3 or 5 a string version of the number will be concatenated onto output. If the number is divisible by 3 "Fizz" is added and "Buzz" is added for numbers divisible by 5. The last line of the each block prints output to the console.
Processes a range of numbers from 0 to limit in a fizzbuzz-like way with arbitrary word/number associations and returns an array of strings.
word_hash keys are integers and their values are strings:
words = { 3 => 'Such', 5 => 'Very', 7 => 'Wow', 11 => 'Shiba'}
doge = arb_fizz 50_000, words
=> [0, 1, 2, Such, 4, Very, Such, Wow, 8, Such, Very, Shiba ...]
To check a value just index into the array:
doge[55] => VeryShiba
Print one value per line to the console as in fizzbuzz:
puts doge
arb_fizz makes the assumption that you will be setting limit at a high number and opts to return an array for manageability. It also makes the assumption that you won't assign 0 (zero) to any words in word_hash because zero divided by anything is 0, which would override every value in the return array - why would you need to calculate that?!
We start with an array called fizz which only contains one item, '0'. For each number from 1 to limit a fresh variable output is assigned to an empty string. Next we create an array of any the keys from word_hash (which are Fixnums) for which the number divided by a key has a remainder of 0 and assign that to the variable matches. For each item in matches concatenate word_hash[match] onto output. If there arent any matches, concatenate the string version of the number onto output. The last step in the loop is to push whatever the value of output is onto our originalfizz array. Once the loop has run for every number return fizz.
