You can take advantage of a basic property of triagle that sum of largest side of triangle < sum of other two sides,
After sorting you could easily deside the range in which possible solution could be found for a chosen hypotenuse On Fri, Oct 14, 2011 at 11:10 AM, ravindra patel <ravindra.it...@gmail.com>wrote: > @Wladimir, yeah I have heard about that.
