Bottom up rod cutting
WebI would then expect the algorithm to cut up your rod into pieces for which you know a positive price. If all of this is correct, the solution is easy. To calculate, say, cutRod (p, 15), first do p = Arrays.copyOf (p, 15 + 1); This will copy p into a new array with indices 0 through 15, padded with zeores. Now run your methods.
