DP and a are arrays of long long type. Shouldn't overflow?

Honestly, during the contest, I coded the solution then ran it for 30,000, found the bound and then set it in the code. It wasn't 200, higher.

That is not true. x can go upto 200 in fact, and 4^200 is much bigger than 20,000. The log4n bound doesnt hold because the 'distributed' ants can came back to the central axis, so its not always decreasing.

Happened with me as well. I should never have ignored those compiler warnings.
