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 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

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 :

student@ubuntu:~/piscine/test$ ./test
125
125
125
125
0
