btreelevelcount

Instructions

Write a function, BTreeLevelCount, that returns the number of levels of the binary tree (height of the tree)

Expected function

func BTreeLevelCount(root *TreeNode) int {

}

Usage

Here is a possible program to test your function :

package main

import (
	"fmt"

	piscine ".."
)

func main() {
	root := &piscine.TreeNode{Data: "4"}
	piscine.BTreeInsertData(root, "1")
	piscine.BTreeInsertData(root, "7")
	piscine.BTreeInsertData(root, "5")
	fmt.Println(piscine.BTreeLevelCount(root))
}

And its output :
