Hi everybody: I don't know why my solution for Prob 550 div 2 fails in this test case. I am getting 2 as expected, and system test got 1. I got WA but maybe system test is wrong, (I don't think so). Thanks in advance.
I sent the same code now in practice rooms and I got 549.88 of 550. How it is posible????
Solution in ideone got 1 too as TopCoder System, for this test case. But, I don't see why!!!
