Question: Create a void returning function, show, which takes one parameter, an immutable Map, and outputs the symbol /shares as shown above except in alphabetical order.

"Create a void returning function, show, which takes one parameter, an immutable Map, and outputs the symbol /shares as shown above except in alphabetical order. Hint: keyes is an Iterable which does not support the sortWith method; convert the keys to a List which does support sortWith."

I'm confused what my professors means by an immutable map. How do I pass that as a parameter.
