// Beautiful code
```

To have something like this :

Hey'

The first issue is to have a type associated with the type std::vector.

const std::vector<HERE_THE_TYPE> countPositivesSumNegatives(const std::vector<HERE_THE_TYPE> input)

They might be some other errors (like the return who might be std::vector ({pos,neg}))
