## btreetransplant
|
||
|
|
|
||
|
|
### Instructions
|
||
|
|
|
||
|
|
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 called 'rplc' in the tree given by root.
|
||
|
|
|
||
|
|
This function must have the following signature.
|
||
|
|
|
||
|
|
### Expected function
|
||
|
|
|
||
|
|
```go
|
||
|
|
func BTreeTransplant(root, node, rplc *TreeNode) *TreeNode {
|
||
|
|
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
### Usage
|
||
|
|
|
||
|
|
Here is a possible [program](TODO-LINK) to test your function :
|
||
|
|
|
||
|
|
```go
|
||
|
|
package main
|
||
|
|
|
||
|
|
import (
|
||
|
|
"fmt"
|
||
|
|
student ".."
|
||
|
|
)
|
||
|
|
|
||
|
|
func main() {
|
||
|
|
root := &student.TreeNode{Data: "4"}
|
||
|
|
student.BTreeInsertData(root, "1")
|
||
|
|
student.BTreeInsertData(root, "7")
|
||
|
|
student.BTreeInsertData(root, "5")
|
||
|
|
node := student.BTreeSearchItem(root, "1")
|
||
|
|
replacement := &student.TreeNode{Data: "3"}
|
||
|
|
root = student.BTreeTransplant(root, node, replacement)
|
||
|
|
student.BTreeApplyInorder(root, fmt.Println)
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
And its output :
|
||
|
|
|
||
|
|
```console
|
||
|
|
student@ubuntu:~/student/btreetransplant$ go build
|
||
|
|
student@ubuntu:~/student/btreetrandsplant$ ./btreetransplant
