• If there is no unique charachters return -1.
• If both strings are empty or one of them return -1.

Expected function

func Weareunique(str1 , str2 string) int {

}

Usage

Here is a possible program to test your function :

package main

import (
	"fmt"
)

func main() {

	arr := [][]string{
		{"foo", "boo"},
		{"abc", "def"},
		{"hello", "yoall"},
		{"everyone", ""},
		{"hello world", "fam"},
	}
	for _, v := range arr {
		fmt.Println(Weareunique(v[0], v[1]))
	}
}

And its output :

$ go run .
2
6
