## basicatoi2

### 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.

### Usage
Here is a possible program to test your function :
```go
package main
import (
"fmt"
piscine ".."
)
func main() {
fmt.Println(piscine.BasicAtoi2("12345"))
fmt.Println(piscine.BasicAtoi2("0000000012345"))
fmt.Println(piscine.BasicAtoi2("012 345"))
fmt.Println(piscine.BasicAtoi2("Hello World!"))
}
```
And its output :
```console
student@ubuntu:~/[[ROOT]]/test$ go build
student@ubuntu:~/[[ROOT]]/test$ ./test
12345
12345
0
0
student@ubuntu:~/[[ROOT]]/test$
```
