Stille Tage fordern uns, die Wirklichkeit neu zu hinterfragen

Yes – the logic can stay the same, you just need to write it so that it works with either type. In practice that means either: * **Make the method generic** – let the compiler infer the type (`T`) and use it for the variable, or * **Overload the method** – write two versions, one that takes a `string` and one that takes a `char`. The body of the method will be identical; only the type of the variable changes. So you can keep the same code for both cases, just adjust the type declaration.
