## btreeisbinary
|
||
|
|
|
||
|
|
### Instructions
|
||
|
|
|
||
|
|
Write a function, BTreeIsBinary, that returns true only if the tree given by root follows the binary search tree properties.
|
||
|
|
|
||
|
|
This function must have the following signature.
|
||
|
|
|
||
|
|
### Expected function
|
||
|
|
|
||
|
|
```go
|
||
|
|
func BTreeIsBinary(root *TreeNode) bool {
|
||
|
|
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
### 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")
|
||
|
|
fmt.Println(student.BTreeIsBinary(root))
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
And its output :
|
||
|
|
|
||
|
|
```console
|
||
|
|
student@ubuntu:~/student/btreeisbinary$ go build
|
||
|
|
student@ubuntu:~/student/btreeisbinary$ ./btreeisbinary
|
||
|
|
true
|
||
|
|
student@ubuntu:~/student/btreeisbinary$
|
||
|
|
```
