Instructions

Write a function ListSize that returns the number of elements in a linked list l.

Expected function and structure

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

type List struct {
	Head *NodeL
	Tail *NodeL
}

func ListSize(l *List) int {

}

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, "2")
	piscine.ListPushFront(link, "you")
	piscine.ListPushFront(link, "man")

	fmt.Println(piscine.ListSize(link))
}
