Today's challenge is inspired by the release of ChatGPT on November 30, 2022.

Given a string of one or more sentences, determine if it was likely generated by AI using the following rules:

• It contains two or more dashes (-).

• It contains two or more sets of parenthesis (()). Text can be within the parenthesis.

• It contains three or more words with 7 or more letters.

• Words are separated by a single space and only consist of letters (A-Z). Don't include punctuation or other non-letters as part of a word.

If the given sentence meets any of the rules above, return "AI", otherwise, return "Human".

--hints--

detectAI("The quick brown fox jumped over the lazy dog.") should return "Human".

assert.equal(detectAI("The quick brown fox jumped over the lazy dog."), "Human");

detectAI("The hypersonic brown fox - jumped (over) the lazy dog.") should return "Human".

assert.equal(detectAI("The hypersonic brown fox - jumped (over) the lazy dog."), "Human");

detectAI("Yes - you're right! I made a mistake there - let me try again.") should return "AI".

assert.equal(detectAI("Yes - you're right! I made a mistake there - let me try again."), "AI");

detectAI("The extraordinary students were studying vivaciously.") should return "AI".

assert.equal(detectAI("The extraordinary students were studying vivaciously."), "AI");

detectAI("The (excited) student was (coding) in the library.") should return "AI".

assert.equal(detectAI("The (excited) student was (coding) in the library."), "AI");

--solutions--

function detectAI(text) {
  const dashCount = (text.match(/-/g) || []).length;
  if (dashCount >= 2) return "AI";

  const parenCount = (text.match(/\([^)]*\)/g) || []).length;
  if (parenCount >= 2) return "AI";

  const words = text.split(" ");
  const longWordCount = words.filter(w => w.replace(/[^A-Za-z]/g, "").length >= 7).length;
  if (longWordCount >= 3) return "AI";

  return "Human";
