Solution

using System;
public class CalculateValuesFunction
{
    public static void Main(string[] args)
    {
        int x1= Convert.ToInt32(Console.ReadLine());
        int x2= Convert.ToInt32(Console.ReadLine());
        int y;
		
        for (int x=x1;x<=x2;x++)
        {
            y= x*x-2*x+1;
            Console.Write("{0} ", y);
        }
    }
}
