I feel like "var" is used for variables, but I can't recall if it can be used for functions too.

I remember practicing a similar question where we had to define a function, and I think "fun" is definitely the right keyword.

I think the correct syntax for defining a function is important here, but I'm not sure if it's "fun" or "var" that should be used.
