Lightbulb Start Watching Lightbulb Start Watching
RU English

This is the second mission in the lightbulb series. I will try to make each following task slightly more complex.

You have already learned how to count the amount of time a light bulb has been on, or how long a room has been lit. Now let's add one more parameter - the counting start time.

This means that the light continues to turn on and off as before. But now, as a result of the function, I want not only to know how long there...

You should be an authorized user in order to see the full description and start solving this mission.
