Do not use the square root function, sqrt . Do not use ^(1/2) or (0.5) . Do not use the "while-break" structure The sample code includes a table output. Use it to help you debug your code. You do not need to generate a table output. Take care of the main part of the problem first, then deal with the special cases .
