Kata

Implement function word_stats that would count number of word occurrence in the given text.

• return hash where every key is a word
• words are lower case and value is a number
• hash must be sorted in the lexical order.

Word has the common meaning. In "The cat is hungry!", the last word is "hungry", not "hungry!" .

Example:

text = "Blow my body blow, the 4 wings in the snow."
word_stats(text) # => {"4"=>1, "blow"=>2, "body"=>1, "in"=>1, "my"=>1, "snow"=>1, "the"=>2, "wings"=>1}
