How to solve a this task with fmt.Stringer
?
Maybe, my decision is not the best:
package main
import "fmt"
type IPAddr [4]byte
func main() {
hosts := map[string]IPAddr{
"loopback": {127, 0, 0, 1},
"googleDNS": {8, 8, 8, 8},
}
for name, ip := range hosts {
fmt.Printf("%v: %v.%v.%v.%v\n", name, ip[0], ip[1], ip[2], ip[3])
}
}
output:
loopback: 127.0.0.1
googleDNS: 8.8.8.8

It asked you to implent a Stringer interface, but you instead change the print statement. I believe that is not what the go Tour asks you to do.
In that and the question, how to do it?

func (ip IPAddr) String() string {
return fmt.Sprintf("%d.%d.%d.%d",ip[0],ip[1],ip[2],ip[3])
}
