nice little functions to get familiar with string & regexp..

deal_with_string.rb

def palindrome? string
  string.gsub(/\W/,"").downcase.reverse == string.gsub(/\W/,"").downcase
end


def count_words string
  result = {}
  string.downcase.split(/\W+/).each do |word|
      result[word] = result[word] ? result[word] + 1 : 1
  end
  result
end
