我的結構如下所示：package mainimport (    "fmt")func main() {    s := Stats{}    s.initStructs()    s.Update()    fmt.Println(s)}type Stats struct {    Languages []Language}type Language struct {    Name       string    Mentions   int    Frameworks []Framework}type Framework struct {    Name     string    Mentions int    Sources  []string}func (s *Stats) Update() {    for _, pl := range s.Languages {        pl.Mentions++        for _, fm := range pl.Frameworks {            fm.Mentions++        }    }}func (s *Stats) initStructs() {    techs := map[string][]string{        "python":     {"flask", "django", "tensorflow", "pytorch"},        "javascript": {"angular", "typescript", "node", "express", "react", "vue", "socket.io"},        "c#":         {"asp.net", "unity", ".net"},        "php":        {"laravel"},        "markup":     {"html", "css", "scss"},        "java":       {"spring", "oracle", "grails", "kotlin", "android"},        "sql":        {"postgre", "mongo", "mysql"},        "c++":        {"unity"}}    for item := range techs {        planguage := Language{Name: item}        for _, i := range techs[item] {            f := Framework{Name: i}            planguage.Frameworks = append(planguage.Frameworks, f)        }        s.Languages = append(s.Languages, planguage)    }}我有一個initStructs()方法讓Stats生成看起來像這樣的嵌套結構{[{python 0 [{flask 0 []} {django 0 []} {tensorflow 0 []} {pytorch 0 []}]} {javascript 0 [{angular 0 [....但是，問題是，每當我嘗試使用Update()方法更新嵌套結構的值時，它不起作用，值不會被更新。我確實意識到我需要使用指針，但不確定如何。
