--description--

Given a string representing the time you set your alarm and a string representing the time you actually woke up, determine if you woke up early, on time, or late.

  • Both times will be given in "HH:MM" 24-hour format.

Return:

  • "early" if you woke up before your alarm time.
  • "on time" if you woke up at your alarm time, or within the 10 minute snooze window after the alarm time.
  • "late" if you woke up more than 10 minutes after your alarm time.

Both times are on the same day.

--hints--

alarm_check("07:00", "06:45") should return "early".

js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(alarm_check("07:00", "06:45"), "early")`)
}})

alarm_check("06:30", "06:30") should return "on time".

js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(alarm_check("06:30", "06:30"), "on time")`)
}})

alarm_check("08:10", "08:15") should return "on time".

js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(alarm_check("08:10", "08:15"), "on time")`)
}})

alarm_check("09:30", "09:45") should return "late".

js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(alarm_check("09:30", "09:45"), "late")`)
}})

alarm_check("08:15", "08:25") should return "on time".

js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(alarm_check("08:15", "08:25"), "on time")`)
}})

alarm_check("05:45", "05:56") should return "late".

js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(alarm_check("05:45", "05:56"), "late")`)
}})

alarm_check("04:30", "04:00") should return "early".

js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(alarm_check("04:30", "04:00"), "early")`)
}})
