BubbleCup 2009

Sry for asking here, but since BubbleCup doesn't have forum I need to put my question here. In the task WhiteStreaks I don't understand test case number 2. In test case number 1 we didn't count rectangle 1x1 in the solution, but in test case number 2 we count rectangle 1x1. So I think that solution to test case number 2 must be 1, but I send my solution to grader and it's wrong. Can someone tell my why is answer for test case number two 2 ?

Thanks in advance,

Aleksandar.

Hm , it seems that my solution is wrong, I found on Timus more test cases. We can count 1x1 as a rectangle...

EDIT: It passed, we can count 1x1 rectangles!
