I have tried to solve Digging
Problem<https://code.google.com/codejam/contest/204113/dashboard#s=p1&a=1>
and
have gotten quite stuck.
When I read the problem, I thought Dijkstra's Algorithm would beat it, and
have tried to do so. But it seems my implementation has many flaws, and is
not giving the required output.


Now, when I read the contest analysis - and I haven't understood the
recurrence behind the DP solution; given the states (as in the analysis)

So in short:
1) Is there a way to solve this using Dijkstra?
2) What's the recurrence behind the DP solution?

Kindly help me.
Thanks.
