## reverse
## **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` .
- 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
```go
package main
type Node struct {
Next *Node
Num int
}
func Reverse(node *Node) *Node {
}
```
### Usage
Here is a possible program to test your function :
```go
package main
import (
"fmt"
)
func pushBack(n *Node, num int) *Node{
}
func main() {
num1 := & piscine.Node{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()
}
```
Its output:
```console
student@ubuntu:~/[[ROOT]]/test$ go build
student@ubuntu:~/[[ROOT]]/test$ ./main
5 -> 4 -> 2 -> 3 -> 1
student@ubuntu:~/[[ROOT]]/test$
```
