Fibonacci

using System;

//Write a program that reads a number n and prints on the console the first n members of the Fibonacci sequence (at a single line, separated by spaces) : 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, …. Note that you may need to learn how to use loops.

class Program
{
    static void Main()
    {
        int lengthFi = int.Parse(Console.ReadLine());
        int tempA = 0;
        int tempB = 1;


        for (int i = 0; i < lengthFi; i++)
        {
           Console.Write(tempA + " ");
           int temp = tempA;
           tempA = tempB;
