Yes, you can find it after click of 3 points right top.

And another option would be comment out your first solution and then write a new one.

Answer 3

Thanks for your answers but when I click on the three points I can only restart the whole course. I would just like to repeat some exercises.
Commenting it out would not help because I don’t know which parts of the code were specified before.
