the type of method binding of golang, when to pass the value and when to pass the pointer?
I have seen the following two ways of writing, but I don"t know how to distinguish between them. Please give me some guidance: 

func (s *Widget) Do() {
  //...
}

func (s Widget) Do() {
  //...
}

package main

import "fmt"

type ABC struct {
    data string
}

//
func (a ABC) delete() {

    a.data = ""
}

//
func (a *ABC) pdelete() {
    a.data = ""
}

func main() {
    A := ABC{"123"}
    fmt.Println(1, A.data)

    //
    A.delete()
    fmt.Println(2, A.data)

    //,
    A.pdelete()
    fmt.Println(3, A.data)

}

/* 
1 123
2 123
3 */
