 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.(AB)
 
 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?

If I understand you correctly, this should do it:

if (($X$A  $Y$A) || ($X$B  $Y$B)):
   // range X-Y is totally outside range A-B
else:
   // range X-Y overlaps A-B partially or totally
endif;

Cheers!

Mike

First of all, take that 'I want to know when you received my e-mail'
-thingie away. It's anoying.

But to the solution:

if ((x  A || x  B)  (y  A || x  B))
{
do something..
}

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.(AB)

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
