Given a time string in "HH:MM" format (24-hour clock), return:

• "Good morning" for times 05:00 to 11:59
• "Good afternoon" for times 12:00 to 17:59
• "Good evening" for times 18:00 to 21:59
• "Good night" for times 22:00 to 04:59

--hints--

getGreeting("06:30") should return "Good morning".

assert.equal(getGreeting("06:30"), "Good morning");

getGreeting("12:00") should return "Good afternoon".

assert.equal(getGreeting("12:00"), "Good afternoon");

getGreeting("21:59") should return "Good evening".

assert.equal(getGreeting("21:59"), "Good evening");

getGreeting("00:01") should return "Good night".

assert.equal(getGreeting("00:01"), "Good night");

getGreeting("11:30") should return "Good morning".

assert.equal(getGreeting("11:30"), "Good morning");

function getGreeting(time) {

  return time;

--solutions--

function getGreeting(time) {
  const [hours, minutes] = time.split(':').map(Number);
  const total = hours * 60 + minutes;

  if (total >= 300 && total < 720) return 'Good morning';
  if (total >= 720 && total < 1080) return 'Good afternoon';
  if (total >= 1080 && total < 1320) return 'Good evening';
