### Instructions

|
- Write a function that simulates the behaviour of the `Atoi` function in Go. `Atoi` transforms a number defined as a `string` in a number defined as an `int`.

|
- Atoi returns `0` if the `string` is not considered as a valid number. For this exercise **only valid** `string` will be tested. They will only contain one or several digits as characters.

|
- This function will **only** have to return the `int`. For this exercise the `error` return of `Atoi` is not required.
