## listsort
6 years ago
### Instructions
Write a function `ListSort` that sorts the linked list by ascending order.
- This time you only will have the `node` structure.
- Try to use recursive.
- Use pointers when ever you can.

### Expected function and structure
```go
type NodeI struct {
Data int
Next *NodeI
}
func ListSort(l *NodeI) *NodeI {
}
```

### Usage
Here is a possible [program](TODO-LINK) to test your function :
```go
package main
import (
"fmt"
piscine ".."
)
func PrintList(l *piscine.NodeI) {
m := l
for m != nil {
fmt.Print(m.Data, " -> ")
m = m.Next
}
fmt.Print(nil)
fmt.Println()
}
func listPushBack(l *piscine.NodeI, data int) *piscine.NodeI {
n := &piscine.NodeI{Data: data}
if l == nil {
return n
}
iterator := l
for iterator.Next != nil {
iterator = iterator.Next
}
iterator.Next = n
return l
}
func main() {
var link *piscine.NodeI
link = listPushBack(link, 5)
link = listPushBack(link, 4)
link = listPushBack(link, 3)
link = listPushBack(link, 2)
link = listPushBack(link, 1)
PrintList(piscine.ListSort(link))
}
```
And its output :
```console
student@ubuntu:~/piscine/test$ go build
student@ubuntu:~/piscine/test$ ./test
1 -> 2 -> 3 -> 4 -> 5 -> <nil>
student@ubuntu:~/piscine/test$
```
