In order to move subtrees around within the binary search tree, write a function, BTreeTransplant
, which replaces the subtree started by node
with the node rplc
in the tree given by root
.
func BTreeTransplant(root, node, rplc *TreeNode) *TreeNode {
}
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")
node := piscine.BTreeSearchItem(root, "1")
rplc := &piscine.TreeNode{Data: "3"}
root = piscine.BTreeTransplant(root, node, rplc)
piscine.BTreeApplyInorder(root, fmt.Println)
}
And its output :
$ go run .
