I'm the first solve of A!!!

But I can't solve CDE. Too hard. Losing rating again.

A>B. Without proving my solution for A, I still solve it slower than B.

    I just printed the bit count array in the last minutes of the contest and hurray; I was lucky enough to figure it out. CP also involves some luck and guesswork at times :((
