|
||
|
|
|
||
|
|
### Instructions
|
||
|
|
|
||
|
|
Write a function to print the value of the root node of a binary tree.
|
||
|
|
You have to create a new number and print the value of data
|
||
|
|
The nodes must be defined as follows:
|
||
|
|
|
||
|
|
### Expected function
|
||
|
|
|
||
|
|
```go
|
||
|
|
type TreeNode struct {
|
||
|
|
left, right *TreeNode
|
||
|
|
data string
|
||
|
|
}
|
||
|
|
|
||
|
|
func PrintRoot(root *TreeNode){
|
||
|
|
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
### Usage
|
||
|
|
|
||
|
|
Here is a possible [program](TODO-LINK) to test your function :
|
||
|
|
|
||
|
|
```go
|
||
|
|
package main
|
||
|
|
|
||
|
|
func main() {
|
||
|
|
//rootNode initialized with the value "who"
|
||
|
|
//rootNode1 initialized with the value "are"
|
||
|
|
//rootNode2 initialized with the value "you"
|
||
|
|
printRoot(rootNode)
|
||
|
|
printRoot(rootNode1)
|
||
|
|
printRoot(rootNode2)
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
And its output :
|
||
|
|
|
||
|
|
```console
|
||
|
|
student@ubuntu:~/piscine/printroot$ go build
|
||
|
|
student@ubuntu:~/piscine/printroot$ ./printroot
|
||
|
|
who
|
||
|
|
are
|
||
|
|
you
|
||
|
|
student@ubuntu:~/piscine/test$
|
||
|
|
```
