Answer 1

1) You're missing the "public class" of your program. Open a new Java code in the code playground and see what's missing.
2) Remember that Sololearn's compiler is not real-time, so you'll need to think ahead and enter all of the input values on a new line when the prompt appears after you hit run; something like this:
1
22
3
4
quit
3) Check how you call your class Jol
