Seems like yours is /slightly/ too slow on Python 3. You can probably make it 
fast enough by only filling half the DP array and sorting to make R < B.

Annoying that they nerfed Python to such an extent, it's practically useless 
now given the amount of extra effort and insight you need to get a valid 
solution, even one that is optimal in big O terms. Perhaps they weren't away 
how many of the Python entries were using Pypy in previous years...

Is there a good reason for excluding Pypy as a platform?
