### 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 **non-valid `string` chains will be tested**. Some will contain non-digits characters.

|
- For this exercise the handling of the signs `+` or `-` does not have to be taken into account.

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