### Usage
Here is a possible [program](TODO-LINK) to test your function :
```go
package main
import (
"fmt"
piscine ".."
)
func main() {
root := &piscine.TreeNode{Data: "4"}
piscine.BTreeInsertData(root, "1")
piscine.BTreeInsertData(root, "7")
piscine.BTreeInsertData(root, "5")
fmt.Println(root.Left.Data)
fmt.Println(root.Data)
fmt.Println(root.Right.Left.Data)
fmt.Println(root.Right.Data)
}
```
And its output :
```console
student@ubuntu:~/piscine/btreeinsertdata$ go build
student@ubuntu:~/piscine/btreeinsertdata$ ./btreeinsertdata
1
4
5
7
student@ubuntu:~/piscine/btreeinsertdata$
```
