 ### Instructions
 
-Write a function that will take a pointer to a array as parameter and overwrites any element that points to `nil`.
+Write a function `Compact` that takes a pointer to a slice of strings as the argument.
+This function must:

+
+- Compact, i.e., delete the elements with `nil` in the slice.
