 puts Hello.best_sentence(sentence,%q{ruby test})

sentence = Array.new
sentence.push("I like ruby")
sentence.push("You like ruby")
sentence.push("We all like ruby")

#! /usr/bin/env ruby
# -*- coding: utf-8 -*-

sentence = Array.new
sentence.push("I like ruby")
sentence.push("You like ruby")
sentence.push("I dont Java")
sentence.push("We all like ruby")


puts sentence.select { |s| s.include?("ruby")}
