listpushback

Instructions

Write a function ListLast that returns the last element of the linked list.

Expected function and structure

type Node struct {
	Data interface{}
	Next *Node
}

type List struct {
	Head *Node
	Tail *Node
}

func ListLast(l *list) *list {
}

Usage

Here is a possible program to test your function :

package main

import (
	"fmt"
	piscine ".."
)


func main() {
	link := &list{}
	link2 := &list{}

	piscine.ListPushBack(link, "three")
	piscine.ListPushBack(link, 3)
	piscine.ListPushBack(link, "1")

	fmt.Println(piscine.ListLast(link).head)
	fmt.Println(piscine.ListLast(link2).head)
}

And its output :

student@ubuntu:~/piscine/test$ ./test
&{1 <nil>}
<nil>
