suppose sorted array is 1,2,3,5,10,12,13,17,19,25
so if u want to find possible combinations, with 25 as hypotenuse, then only range 10 ... 19 could have answer as 19 + 10 > 25 On Fri, Oct 14, 2011 at 3:14 PM, Ankur Garg <[email protected]> wrote: > @Rahul > > Pls elaborate with an example ... > > > On Fri, Oct 14, 2011 at 2:35 PM, rahul patil < > [email protected]> wrote: > >> 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 < >> [email protected]> wrote: >> >>> @Wladimir, yeah I have heard about that.
