+// example that takes two parameters. As you can see, parameters
+// are declared just like an other types ("name": "type"):
+//
+//     fn myFunction( number: u8, is_lucky: bool ) {
+//         ...

+// Please give this function the correct input parameter(s).
+// You'll need to figure out the parameter name and type that we're
