Implement the following types and define ServeHTTP methods on them. Register them to handle specific paths in your web server.

type String stringtype Struct struct {    Greeting string    Punct    string    Who      string}

For example, you should be able to register handlers using:

http.Handle("/string", String("I'm a frayed knot."))http.Handle("/struct", &Struct{"Hello", ":", "Gophers!"})

package mainimport (    "net/http"    "fmt")type String stringtype Struct struct {    Greeting string    Punct    string    Who      string}func (h Struct) ServeHTTP(    w http.ResponseWriter,    r *http.Request) {    fmt.Fprint(w, h)}func (s String) ServeHTTP(    w http.ResponseWriter,    r *http.Request) {    fmt.Fprint(w, s)}func main() {    http.Handle("/string", String("I'm a frayed knot."))    http.Handle("/struct", &Struct{
   "Hello", ":", "Gophers!"})    // your http.Handle calls here    http.ListenAndServe("localhost:4000", nil)}
