Hi everybody i am trying to solve problem http://acm.uva.es/p/v105/10512.html.
my solution is (x+y)y=P (1) (x-y)x=Q (2) (1+(y/x))xy=P (1)//taking x outside (1-(y/x))x^2=Q (2) dividing 1 and 2 and let (y/x)=k (1+k)k/(1-k)=P/Q; solving for k k=-(P+Q) +-sqrt((P+Q)^2+4PQ)/2Q; since x>=y so we can not take -ve sign as it will make |k|>1 which is not possible so i take only +ve sign ; solution is possible only when (P+Q)^2+4PQ is perfect square . after determining k we can find out x and y so my values are x=+-sqrt(Q/(1-k)); and y=+-sqrt(Pk/(1+k)); now my problem is based on for each value of x we have two values of y so we have 4 pair of values .So which value to output . thnkx in advance . --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.
