Figured i would get most replies here!
Trying to understand this algorithm:
And i don't understand the solution, i've dry run it a few times but i seem to get stuck. I don't understand where the numbers which the backwards arrow(s) point to in the solution, can anyone help?
Here is the soln.
Cheers
