 public static void Main()
 {
    int binary;
   int weight=1;
   int number=0;
   int rem;
   Console.WriteLine('enter the binary number');
   binary=int.Parse(Console.ReadLine());
   while(binary!=0)
   {
           rem=binary%10;
           number=number+rem*weight;
           binary=binary/10;
           weight *=2;
   }
