## addlinkednumbers ## **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 have two numbers represented by a linked list, where each node contains a single digit. The digits are stored in reverse order, such that the 1’s digit is at the head of the list. Write a function that adds the two numbers and returns the sum as a linked list ### Expected function and structure ```go package main type Node struct { Next *Node Num int } func AddLinkedNumbers(num1, num1 *Node) *Node { } ``` ### Usage Here is a possible program to test your function: ```go package main import ( "fmt" ) func pushFront(node *Node, num int) *Node { // ... // Write yourself } func main() { // 3 -> 1 -> 5 num1 := &Node{Num:5} num1 = pushFront(num1, 1) num1 = pushFront(num1, 3) // 5 -> 9 -> 2 num2 := &Node{Num:2} num2 = pushFront(num2, 9) num2 = pushFront(num2, 5) // 9 -> 0 -> 7 result := AddLinkedNumbers(num1, num2) for tmp := result; tmp != nil; tmp = tmp.Next { fmt.Print(tmp.Num) if tmp.Next != nil { fmt.Print(" -> ") } } fmt.Println() } ``` An its output: ```console student@ubuntu:~/[[ROOT]]/test$ go build student@ubuntu:~/[[ROOT]]/test$ ./main 9 -> 0 -> 7 student@ubuntu:~/[[ROOT]]/test$ ```
