@Blue Mary (and other solvers of the task) : what is your sentiment about riddle section for this one ? I really waiting for. Thanks in advance. I think it belongs to. But as it's a good problem, we can consider in a near future make a classical edition. Not now, not to spoil on its content... |

There is a new "riddle" section, after "classical", "challenge", ... What about moving this very good problem to "riddle" ? |
