Student pass all cucumber and rspec tests without setting flash

[rosewcs345]

Apparently, there are no tests that check to see that the flash is getting set at all (let alone, properly).

If I take a proper solution and substitute this code for the guess method in app.rb, all the tests still pass:

    # Use existing methods in HangpersonGame to process a guess.
    # If a guess is repeated, set flash[:message] to "You have already used that letter."
    # If a guess is invalid, set flash[:message] to "Invalid guess."
    post '/guess' do
      begin
        letter = params[:guess].to_s[0] #this code was given
        #flash[:message] = "You have already used that letter." if ! @game.guess(letter)
        valid = @game.guess(letter)
      rescue ArgumentError
        #flash[:message] = "Invalid guess."
      end
      redirect '/show'
    end
