### Instructions
|

|
- For this exercise the handling of the signs + or - **has** to be taken into account. If one of the signs is encountered before any number it should determine the sign of the returned `int`.

|

|
- This function will **only** have to return the `int`. In case of invalid input, the function should return `0`.
