# listpushback
|
||
|
|
|
||
|
|
## Instructions
|
||
|
|
|
||
|
|
Write a function `ListAt` that haves one pointer to the list, `l`, and an `int` as parameters. This function should print a `Node` of the linked list, depending on the number, `nbr`.
|
||
|
|
|
||
|
|
- In case of error it should print `nil`
|
||
|
|
|
||
|
|
## Expected function and structure
|
||
|
|
|
||
|
|
```go
|
||
|
|
type Node struct {
|
||
|
|
Data interface{}
|
||
|
|
Next *Node
|
||
|
|
}
|
||
|
|
|
||
|
|
|
||
|
|
func ListAt(l *Node, nbr int) *Node{
|
||
|
|
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
Here is a possible [program](TODO-LINK) to test your function :
|
||
|
|
|
||
|
|
```go
|
||
|
|
package main
|
||
|
|
|
||
|
|
import (
|
||
|
|
"fmt"
|
||
|
|
piscine ".."
|
||
|
|
)
|
||
|
|
|
||
|
|
func main() {
|
||
|
|
link := &Node{}
|
||
|
|
|
||
|
|
ListPushBack(link, "hello")
|
||
|
|
ListPushBack(link, "how are")
|
||
|
|
ListPushBack(link, "you")
|
||
|
|
ListPushBack(link, 1)
|
||
|
|
|
||
|
|
fmt.Println()
|
||
|
|
|
||
|
|
fmt.Println(ListAt(link, 3).Data)
|
||
|
|
fmt.Println(ListAt(link, 1).Data)
|
||
|
|
fmt.Println(ListAt(link, 7))
|
||
|
|
}
|
||
|
|
|
||
|
|
```
|
||
|
|
|
||
|
|
And its output :
|
||
|
|
|
||
|
|
```console
|
||
|
|
student@ubuntu:~/piscine/test$ go build
|
||
|
|
student@ubuntu:~/piscine/test$ ./test
|
||
|
|
you
|
||
|
|
hello
|
||
|
|
<nil>
|
||
|
|
student@ubuntu:~/piscine/test$
|
||
|
|
```
|
