Man I was so close to this solution but unfortunately I didn't realize that you need to add a parenthesis enclosing all the statements.

Just one look and i've already understood what its doing. Kudos.

did you just make a function inside a function?

Just when I thought that one line is impossible.

Great code but it can be more cleaner by using a more advanced syntax such as the ternary operator(?). The turnary operator is a shortcut for if then else statements.
This is the format.
if condition ? then code: else code;
Usng it as a lambda expression returns the codes result.

Damn, code is very minimal. Perfect execution. Just shows how unefficient I am.
