3 for random three digit number, 6 for random six digit number, 9 for random nine digit number.
Practically, I had some homework where I had to create my own problems and solve it, and, you know, I just had no idea what to do. Then it hit me. I created a project on MakeCode to generate 3, 6, 9, and 12 digit numbers. this is just a version of it.
