Binary Tree Node struct with LeetCode compatible Serialize / Deserialize format

go get github.com/egregors/TreeNode

This package provides TreeNode data struct and a few function for serialization and deserialization respectively.

package main

import (
	"log"

	tn "github.com/egregors/TreeNode"
)

func main() {
	data := "[1,2,3,null,null,4,5]"
	root, err := tn.NewTreeNode(data)
	if err != nil {
		log.Fatal(err)
	}

	root.Right.Left.Val = 42
	newData := root.String()
	...
}

A NewTreeNode(data string) (*TreeNode, error) constructor expect LeetCode style formatted string. Otherwise, to serialize a tree just call String() for TreeNode object.
