## **WARNING! VERY IMPORTANT!**
For this exercise a function will be tested **with the exam own main**. However the student **still needs** to submit a structured program:
This means that:
- The package needs to be named `package main`.
- The submitted code needs one declared function main(```func main()```) even if empty.
- The function main declared needs to **also pass** the `Restrictions Checker`(illegal functions tester). It is advised for the student to just empty the function main after its own testings are done.
- Every other rules are obviously the same than for a `program`.
### Instructions
Write a function that takes a `string` number and its `string` base in parameters and returns its conversion as an `int`.
If the base or the `string` number is not valid it returns `0`
Validity rules for a base :
- A base must contain at least 2 characters.
- Each character of a base must be unique.
- A base should not contain `+` or `-` characters.
Only valid `string` numbers will be tested.
The function **does not have** to manage negative numbers.
### Expected function
```go
func AtoiBase(s string, base string) int {
}
```
### Usage
Here is a possible program to test your function :
```go
package main
import (
"fmt"
)
func main() {
fmt.Println(AtoiBase("125", "0123456789"))
fmt.Println(AtoiBase("1111101", "01"))
fmt.Println(AtoiBase("7D", "0123456789ABCDEF"))
fmt.Println(AtoiBase("uoi", "choumi"))
fmt.Println(AtoiBase("bbbbbab", "-ab"))
}
```
And its output :
```console
student@ubuntu:~/test$ go build
student@ubuntu:~/test$ ./test
125
125
125
125
0
student@ubuntu:~/test$
```
