Today's contest was tough and constructive heavy !! When there are constructive problems; practice count doesn't matter much.. If the solution hits you; it hits you !!
We went over this before.
Also you should realise that you may be weak/lack some core intuition about binary. You just found out a major drawback! You should focus this anger toward patching it ASAP!
Bro i couldn't come up with a sol'n to C which happens to be bit masking, how should i improve on that?
you should think about xor, & and | in your free time. This problem for instance was just about reformulating the complicated looking formula. If I were you, I would start with thinking about when x+y = x^y.
Practice bitwise problems
its not all about bitwise.I got 500 points from B
I feel you, had one of my worst performance today, gonna drop to expert T_T
I solved 300+ problems when I dropped out of specialist, then I thought I'm retarded too...
But I simply choose not to give up for now.
Hang in there brother.
