  Convert binary to decimal number
*/
public class DecimalNumber
{
	public void binaryTodecimal(String number)
	{
		// Assuming that number contains 0,1s
		// Used to store result
		var result = 0;
		var bit = 0;
		var n = number.Length - 1;
		// Display Binary number
		Console.Write("Binary :  {0}", number);
		// Execute given number in reverse order
		while (n >= 0)
		{
			if (number[n] == '1')
			{
				// When get binary 1
				result += (1 << (bit));
			}
			n = n - 1;
			// Count number of bits
			bit++;
		}
		// Display decimal result
		Console.WriteLine("  Decimal :  {0}", result);
	}
	public static void Main(String[] args)
	{
		var task = new DecimalNumber();
		// Test Cases
		task.binaryTodecimal("1111");
		task.binaryTodecimal("10111");
		task.binaryTodecimal("10101");
		task.binaryTodecimal("1001");
		task.binaryTodecimal("1101");
	}
}
