Instructions

Write a function, BTreeMin, that returns the node with the minimum value in the tree given by root

This function must have the following signature.

Expected function

func BTreeMin(root *TreeNode) *TreeNode {

}

Usage

Here is a possible program to test your function :

package main

import (
  "fmt"
  student ".."
)

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

And its output :

student@ubuntu:~/student/btreemin$ go build
student@ubuntu:~/student/btreemin$ ./btreemin

student@ubuntu:~/student/btreemin$
