# Stuck on problems in coding

i’ve been stuck on this for a long time and id appreciate any help on these, especially question three where i don’t know where to begin.QUESTIONS.mov - Google Drive

This video from the link is hard to deal with.
That may be one of the reasons why there are no replies yet.

You can:

• post the problem
• post your code(what have you tried)
• provide some of your thoughts about it - if it does not work - why do you think that is the case
• if you ‘don’t know where to begin’, and there is no code - there should be the way to try and ask specific question about the problem

Also would be a good idea to discuss one coding problem in one thread, not a bunch of them at once.

I have uplaoded two screenshots of the proble at hand. I do not know where to start for this and what kind of way to complete the calcMissing function so that it has 20 rows

Please post actual code instead of pictures. Thanks

here is what i have tried so far for question 1, but it does not work and has a runtime error: Screen Recording 2022-09-12 at 5.16.02 PM.mov - Google Drive
