trimatoi

Instructions

• Write a function that transforms numbers within a string, into an int.

• If the - sign is encountered before any number it should determine the sign of the returned int.

• This function should only return an int. In the case of an invalid input, the function should return 0.

• Note: There will never be more than one sign in a string in the tests.

Expected function

func TrimAtoi(s string) int {

}

Usage

Here is a possible program to test your function :

package main

import (
	"fmt"
	"piscine"
)

func main() {
	fmt.Println(piscine.TrimAtoi("12345"))
	fmt.Println(piscine.TrimAtoi("str123ing45"))
	fmt.Println(piscine.TrimAtoi("012 345"))
	fmt.Println(piscine.TrimAtoi("Hello World!"))
	fmt.Println(piscine.TrimAtoi("sd+x1fa2W3s4"))
	fmt.Println(piscine.TrimAtoi("sd-x1fa2W3s4"))
	fmt.Println(piscine.TrimAtoi("sdx1-fa2W3s4"))
	fmt.Println(piscine.TrimAtoi("sdx1+fa2W3s4"))
}

And its output :

$ go run .
12345
12345
12345
0
1234
-1234
1234
1234
$
