Instructions

Write a function to print the value of the root node of a binary tree. The nodes must be defined as follows:

Expected function

type TreeNode struct {
	left, right *TreeNode
	data        string
}

func PrintRoot(root *TreeNode){

}

Usage

Here is a possible program to test your function :

package main

func main() {
	// rootNode initialized with the value "who"
	// rootNode1 initialized with the value "are"
	// rootNode2 initialized with the value "you"
	printRoot(rootNode)
	printRoot(rootNode1)
	printRoot(rootNode2)
}

And its output :

$ go run .
who
are
you
$
