golang 笔记

---

func main()  {

   var root treeNode

   //root = treeNode{value:3}

   //root.left = &treeNode{}

   //root.right = &treeNode{5,nil,nil}

   //root.right.left=new(treeNode)

   nodes :=[]treeNode{

      {value:3},

      {},

      {left:&root},

      {6,nil, &root},

   }

   fmt.Println(nodes)

}

[{3 <nil> <nil>} {0 <nil> <nil>} {0 0xc00004a420 <nil>} {6 <nil> 0xc00004a420}]

工厂

func createNode(value int)  *treeNode{

   return  &treeNode{value:value}

}

golang 的所有参数都是传值

直接调用setValue()
