You only need to combine the String "Hello " and the contents of the name URL parameter in the get route body here.

hello method isn't needed for this challenge. Sometimes we write helper function if it helps to reduce the program's complexity, but for a simple problem like this one, helper function is overkill and only makes code more complicated than it needs to be.

require "sinatra"

get "/greet/:name" do
  # YOUR CODE HERE
  "Hello " + params[:name]
end

Hope it helps.

Thank you so much)
