# Shortest String

# I worked on this challenge [by myself].

# shortest_string is a method that takes an array of strings as its input
# and returns the shortest string
#
# +list_of_words+ is an array of strings
# shortest_string(array) should return the shortest string in the +list_of_words+
#
# If +list_of_words+ is empty the method should return nil

#Your Solution Below
def shortest_string(list_of_words)
  shortest = list_of_words[0]

  list_of_words.each do |word|
    if word.length < shortest.length
      shortest = word
    end
  end

  return shortest
end


#Refactored
def shortest_string(list_of_words)
  list_of_words.sort_by! {|word| word.length}
  return list_of_words[0]
end
