如何在golang中编写包含嵌套递归数据的结构

package main

import "fmt"

type TreeNode struct {
    Value    int
    Children []*TreeNode
}

func main() {
    // 创建一个包含嵌套递归数据的结构
    root := &TreeNode{
        Value: 1,
        Children: []*TreeNode{
            {
                Value: 2,
                Children: []*TreeNode{
                    {Value: 4, Children: nil},
                    {Value: 5, Children: nil},
                },
            },
            {
                Value: 3,
                Children: []*TreeNode{
                    {Value: 6, Children: nil},
                    {Value: 7, Children: nil},
                },
            },
        },
    }

    // 打印结构中的数据
    printTree(root)
}

func printTree(node *TreeNode) {
    fmt.Println(node.Value)
    for _, child := range node.Children {
        printTree(child)
    }
}
