## **WARNING! VERY IMPORTANT!**
For this exercise a function will be tested **with the exam own main**. However the student **still needs** to submit a structured program:
This means that:
- The package needs to be named `package main`.
4 years ago
- The submitted code needs one declared function main(`func main()`) even if empty.
- The function main declared needs to **also pass** the `Restrictions Checker`(illegal functions tester). It is advised for the student to just empty the function main after its own testing are done.

- Every other rules are obviously the same than for a `program`.
### Instructions
You are given a linked list, where each node contains a single digit.
Write a function that reverses the list and returns pointer/reference to new linked list
### Expected function and structure
5 years ago
```go
package main
5 years ago
5 years ago
type NodeAddL struct {
Next *NodeAddL
Num int
5 years ago
}
5 years ago
func Reverse(node *NodeAddL) *NodeAddL {
5 years ago
}
```
### Usage
Here is a possible program to test your function :
5 years ago
```go
package main
import (
4 years ago
"fmt"
5 years ago
)
5 years ago
func pushBack(n *NodeAddL, num int) *NodeAddL{
}
5 years ago
func main() {
4 years ago
num1 := &piscine.NodeAddL{Num: 1}
num1 = pushBack(num1, 3)
num1 = pushBack(num1, 2)
num1 = pushBack(num1, 4)
num1 = pushBack(num1, 5)
result := piscine.Reverse(num1)
for tmp := result; tmp != nil; tmp = tmp.Next {
fmt.Print(tmp.Num)
if tmp.Next != nil {
fmt.Print(" -> ")
}
}
fmt.Println()
5 years ago
}
```
Its output:
```console
student@ubuntu:~/[[ROOT]]/test$ go build
student@ubuntu:~/[[ROOT]]/test$ ./main
5 years ago
5 -> 4 -> 2 -> 3 -> 1
student@ubuntu:~/[[ROOT]]/test$
5 years ago
```
