--description--

Given a number of seconds, return the duration in spoken English.

• Break the duration into hours, minutes, and seconds.
• Skip any zero values.
• Use singular or plural as appropriate ("1 hour", "2 hours").
• If present, join the last two units with "and", and the second and third to last units with a comma ("1 hour, 2 minutes and 3 seconds").

--hints--

getSpokenDuration(3723) should return "1 hour, 2 minutes and 3 seconds".

assert.equal(getSpokenDuration(3723), "1 hour, 2 minutes and 3 seconds");

getSpokenDuration(7295) should return "2 hours, 1 minute and 35 seconds".

assert.equal(getSpokenDuration(7295), "2 hours, 1 minute and 35 seconds");

getSpokenDuration(8521) should return "2 hours, 22 minutes and 1 second".

assert.equal(getSpokenDuration(8521), "2 hours, 22 minutes and 1 second");

getSpokenDuration(435) should return "7 minutes and 15 seconds".

assert.equal(getSpokenDuration(435), "7 minutes and 15 seconds");

getSpokenDuration(14455) should return "4 hours and 55 seconds".

assert.equal(getSpokenDuration(14455), "4 hours and 55 seconds");

getSpokenDuration(72000) should return "20 hours".

assert.equal(getSpokenDuration(72000), "20 hours");

getSpokenDuration(1) should return "1 second".

assert.equal(getSpokenDuration(1), "1 second");
