atoibase

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 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.

String number must contain only elements that are in base.

Only valid string numbers will be tested.

The function does not have to manage negative numbers.

Expected function

func AtoiBase(s string, base string) int {

}

Usage

Here is a possible program to test your function :

package main

import (
	"fmt"
	"piscine"
)

func main() {
	fmt.Println(piscine.AtoiBase("125", "0123456789"))
	fmt.Println(piscine.AtoiBase("1111101", "01"))
	fmt.Println(piscine.AtoiBase("7D", "0123456789ABCDEF"))
	fmt.Println(piscine.AtoiBase("uoi", "choumi"))
	fmt.Println(piscine.AtoiBase("bbbbbab", "-ab"))
}

And its output :

$ go run .
125
125
125
125
0
$
