listpushback

Instructions

Write a function ListPushBack that inserts a new element NodeL at the end of the list l while using the structure List.

Expected function and structure

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

type List struct {
	Head *NodeL
	Tail *NodeL
}

func ListPushBack(l *List, data interface{}) {

}

Usage

Here is a possible program to test your function :

package main

import (
	"fmt"
	piscine ".."
)

func main() {

	link := &piscine.List{}

	piscine.ListPushBack(link, "Hello")
	piscine.ListPushBack(link, "man")
	piscine.ListPushBack(link, "how are you")

	for link.Head != nil {
		fmt.Println(link.Head.Data)
		link.Head = link.Head.Next
	}
}

And its output :

student@ubuntu:~/[[ROOT]]/test$ ./test
Hello
man
how are you
student@ubuntu:~/[[ROOT]]/test$
