Re: [QUIZ] Micrrowave Numbers (#118

How is the microwave supposed to know that "120" is 120 seconds but
"200" is two minutes? My experience is that microwaves will interpret
two-digit numbers as seconds and three-digit numbers as minutes and
seconds. Therefore, "99" is 99 seconds, but "120" is one minute, twenty
seconds. Am I missing something?

Hmm, these are good points. Let's just focus on the two number
scenarios for the purpose of this quiz then.

It's still possible to use larger numbers, just a bit of math is needed.

For example, 4:09 can also be 3:69, with the latter being a much
shorter distance. On the flip side, compare 12:33 with 11:93, where
the former is shorter.

I think the confusion is that I specified input and output to both be
integers, but they don't really mean the same thing.

Input is always seconds... two minutes is "120", five minutes is
"600". Input is NOT the keys you would press.

Output is always the keys to press... It would have been clearer,
perhaps, if I requested the output as an array such as [1, 2, 0,
:cook], or even a string like "120*". When I proposed the problem, I
realized that the "*" (cook) button is always part of the output, so I
could have the function return an integer and the "*" would be
implicit. But this, I think, confused things.

So 120 (or "120*") as output means to push, in order, the buttons 1,
2, 0 and *. Which, for a microwave means 1:20, or 80 seconds.

Does this clear things up?

The input is always "desired seconds", so 200 as input means 3 mins,
20 secs, and 120 as input means 2 mins.

The output is always "buttons to press", so 200 as output always means
2:00, and 120 _as output_ means 1:20.

And the convention for this quiz (not well specified, sorry) is that
if the buttons I press on the microwave are 170, the microwave will
treat that as 1:70... it will first countdown 70 seconds to 1:00,
then 0:59, 0:58... etc.

Here's a thought: for times from 0-99 seconds, determine the fastest way
of typing those times.

For times above 99 seconds, do as follows:
min,sec=thetime.divmod(60)
min-=1
sec+=60
and compute the distances that way.
