Write a function that takes an array of words and smashes them together into a sentence and returns the sentence. You can ignore any need to sanitize words or add punctuation, but you should add spaces between each word. Be careful, there shouldn't be a space at the beginning or the end of the sentence!
['hello', 'world', 'this', 'is', 'great'] => 'hello world this is great'
def smash(words)
words.join(' ')
end
def smash(words)
words * ' '
end
