The Exercism.io word-count problem: Write a program that given a phrase can count the occurrences of each word in that phrase. For example for the input `"olly olly in come free"` ```plain olly: 2 in: 1 come: 1 free: 1 ```
# Where I ended up...
class Phrase < String
def word_count
words.each_with_object(Hash.new(0)) { |word, word_count| word_count[word] += 1 }
end
def words
downcase.scan(/\w+/)

Exercise 1 from Exercism.io - Bob Bob answers 'Sure.' if you ask him a question. He answers 'Whatever.' if you tell him something. He answers 'Woah, chill out!' if you yell at him (ALL CAPS). He says 'Fine. Be that way!' if you address him without actually saying anything.
# Where I ended up...
class Bob
def hey input
talking = Phrase.new(input)
return 'Fine. Be that way.' if talking.silent?
return 'Woah, chill out!' if talking.yelling?
