Exercise 5.38:

Function SquareRoot

Objetive:

Create a function SquareRoot, to calculate and return the approximated Square Root of an integer number, between two specified values:

Console.Write( SquareRoot(82, 2, 12) );

would try to find the square root of 82, trying values between 2 and 12, so it would return 9

public class Main
{
	public static int SquareRoot(int number, int min, int max)
	{
		int result = 0;
		for (int i = min; i <= max; i++)
		{
			if ((i * i) <= number)
			{
				result = i;
			}
		}

		return result;
	}

	public static void main(String[] args)
	{
		System.out.println(SquareRoot(82, 2, 12));
		System.out.println(SquareRoot(99, 2, 12));
		System.out.println(SquareRoot(100, 2, 12));
		System.out.println(SquareRoot(101, 2, 12));
	}
}
