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.

Expected function

func BasicAtoi2(s string) int {

}

Usage

Here is a possible program to test your function :

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 :

$ go run .
12345
12345
0
0
$
