in reply to Re^3: Iterating over hash to find specific key to sum up the cost (updated)
in thread Iterating over hash to find specific key to sum up the cost
anyway I don't understand the requirement "sums up to 430" either.
See the last update at the top of my node: the cost keys did originally sum up to 430.
Update:
FWIW: This old node shows a recursive walker to dive into a randomly nested structure.
I've also got some "diver" type code if you search for "dive" on my scratchpad.
