Can someone help me with the swift question please.

1.1

In order to make any changes made to a parameter persist after a function has returned, the parameter must be declared using the ___________ keyword. Parameters passed to a function that are declared without the ___________ keyword cannot have their values changed by the function.

What is the keyword that goes in the blank above that allows a parameter passed to a function to be changed by the function and have the change persist after the function returns?
