Problem 2470. self description 2.0

Hello,
You seem to be unstoppable in Cody, so I have a challenge for you.
See Problem 908 (AVIRIS Inscribed Rectangle Bit Mask) by the great Richard Zapor.
The url is dead in test n°5, but you know that some methods exist to bypass this (See the Singularity series by Alfonso).

I am looking for a more sophisticated solution where I give a correct algorithm for this problem AND at the same time pass this test as if nothing happened. You can find a correct url of the AVIRIS file in problem 898.
So how to proceed to exchange the two urls ? I don't know if it's possible because the time constraints are high.
Good luck !!

Thanks. And thats really tough...

use builtin,so I overload all the eq, but failed
