Problem A of Gym is giving me a lot of trouble. I have reviewed my code multiple times and after several Wrong Answers I can't see the mistake. Any help is appreciated :) My submission

You did offset to avoid negative weights, but you actually don't avoid wmax > 802.
For example, in test
10000 500
1 1 100
1 1 100
...
// p[i] = 1, w[i] = 1, d[i] = 100 for all items
You will have in process states with wmax = 500 + 300 + 99 and 500 + 300 + 99 * 2, but your dp has sizes 10002 x 802 x 3. It is not good because you have line in your code:
So you need to change second dimension of dp to m + 2 * 300 or something about it.
P.S. Actually, this code with increasing of second dp dimension gives TL, because check
doesn't return "-INF" results and process "-INF" states every time. You need to change this code to:
to process only "-1" states.
Understood! Thank you very much, accepted now :) I will have more care with these "weird jumping" DP excercises the next time.
