What is the point?

I think it's nice to understand a simple good again, like motivation, after loosing and failing harder codes again and again.

I think the repetition is a good thing. in sports and martial arts, they drill the basics into you until you can recite it in your sleep. That's the idea here. To truly master anything you must first master the basics. I knew those teachings from Uncle Iroh would come in handy one day XD

to get the muscle memory because over the period of time if there is no if the basics are not on our toes we may ruin the bigger code in future as said "many big programmers find errors at the basic code".

Note rude to ask, but there are elements in these questions that are used over and over and they all build on each other. The repetition is deliberate to help drill certain parts of the syntax into your head. It's very easy to complete a simple task or two one day and then come back some time later and have forgotten most of what you've "learned"!

During these tasks, you can think about how to complete them faster: use shortcuts and live templates in IDEA, save code snippets in a separate place, etc.

It is so that it will stay in our muscle memory I think and will help us better remember the code. Our brain can easier go back think of it like driving an bus or a car, We remember how to drive because it is an repetitive task which we have done many times.
