+In variables3 we already learned how to make an immutable variable mutable
+using a special keyword. Unfortunately this doesn't help us much in this exercise
+because we want to assign a different typed value to an existing variable. Sometimes
+you may also like to reuse existing variable names because you are just converting
+values to different types like in this exercise.
+Fortunately Rust has a powerful solution to this problem: 'Shadowing'!
+You can read more about 'Shadowing' in the book's section 'Variables and Mutability'.
+Try to solve this exercise afterwards using this technique."""
