listpushfront

Instructions

Write a function ListPushFront that inserts a new element NodeL at the beginning 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 ListPushFront(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.ListPushFront(link, "Hello")
	piscine.ListPushFront(link, "man")
	piscine.ListPushFront(link, "how are you")

	it := link.Head
	for it != nil {
		fmt.Print(it.Data, " ")
		it = it.Next
	}
	fmt.Println()
}

And its output :

student@ubuntu:~/piscine-go/test$ ./test
how are you man Hello
