Hi some logic help is required!!!!!

Hi friend, I need some help on this logic... 1. I have some range (A to B) which is fixed and A,B are very large numbers.(A<B) 2. I have X to Y and I want to check this range should not match with A to B. How can I check this? Ex: 1) A=4 B=8 Totally 4 cases will come!! X=2 Y=5 X=5 Y=6 X=2 Y=9 X=6 Y=9 In all the above cases that logic should return false. How can I solve this?? Don't use for loop!!!!!(Because those are very large numbers (chrores)) And logic should be simple and cute!!!!! Cheers Balaji
