Here is a possible program to test your function :
|
||
![]()
5 years ago
|
|
||
|
```go
|
||
|
package main
|
||
|
|
||
|
import (
|
||
![]()
5 years ago
|
"fmt"
|
||

|
piscine ".."
|
||
![]()
5 years ago
|
)
|
||
|
|
||
|
func main() {
|
||
5 years ago
|
root := &piscine.TreeNode{Data: "4"}
|
||
|
piscine.BTreeInsertData(root, "1")
|
||
|
piscine.BTreeInsertData(root, "7")
|
||
|
piscine.BTreeInsertData(root, "5")
|
||
|
fmt.Println(piscine.BTreeIsBinary(root))
|
||
![]()
5 years ago
|
}
|
||
|
```
|
||
|
|
||
|
And its output :
