Answer 1

1. You can remove lines 5 and 6. 1 they don't need !! as they're already unwrapped non-null. 2 they don't do anything as they're not saved back to the variables.

2. Your error is due to the use of parentheses ( ) for your nested else block instead of curly braces { }.

Answer 2

ChaoticDawg well, thanks a lot, I haven't noticed such error

Answer 3

ChaoticDawg well, but when I run it the case #4 gives me an error, do you know someone's code from which I can try to realize my mistake?
