How can I do this homework?

[debxyz]

Hello @add

Please read through THE FORUM’S GUIDELINES on how to ask your questions:

Guidelines—Asking Questions

Summary (TL;DR) Ask complete questions to get better answers! Be specific. For example: I want to load an image. I tried using createImg() , and I expected the image to be on canvas, but what happened instead was the image showing up below the canvas. Isolate your problem and work in small steps. Share only the code directly related to your problem if it is part of a bigger project, and if something isn’t working, try the smallest code that could do the thing you want. Can we run your code …

Posting your homework question without showing any attempt at breaking down the problem is basically asking us to do your homework for you. And I doubt you want that.

Help us help you by showing us what you know or can do at this point, even if you think it’s wrong. We can then build from that.
