    - Elimina el parámetro de entrada `_name` para que `_generateRandomDNA` no acepte ningún parámetro.
-   - En el cuerpo de la función `_generateRandomDNA`, remplaza `_name` por `battleCount`. Ahora puedes recordar de [Lección 1, Capitulo 11](https://vyper.fun/#/1/keccak256-and-typecasting), que `keccak256` espera un único parámetro de tipo `bytes32`, `Bytes` o `String`. Entonces, necesitamos usar `convert` para castear `battleCount` a `bytes32`.
