######Render => "the Bridge Over the River Kwai"

######Expected rendering => "The Bridge Over the River Kwai"

Hello i present you my piece of code, the rendering gives "the Bridge Over the River Kwai" While I would like "The Bridge Over the River Kwai" So I would like to find a way to find an exception on the same word.

Answer 1

Your code, but always capitalise the first letter, using each_with_index to get the position in the array:

def titleize(string)
  nocaps = ["the","and"]
  string.split(" ").each_with_index.map { |word, i| i.positive? && nocaps.include?(word) ? word : word.capitalize }.join(" ")
end

titleize("the bridge over the river kwai")
