public double squareRoot(double x)
    {
        double epsilon = 0.000001;
        double base = 0;
        double increment = 1;
        while (increment > epsilon)
        {
            double diff = base*base - x;
            if (diff  0)
            {
                base -= increment;
                increment /= 10;
            }
            else
            {
                break;
            }
        }
        return base;
    }

private static double sqrt(double n)
	{
		double lower = 0;
		double upper = n;
		for (int i = 0; i < 1000; i++)
		{
			double mid = (lower + upper) / 2;
			if (mid * mid < n)
				lower = mid;
			else upper = mid;
		}
		return (lower + upper) / 2;
	}
