what if other people say the same thing from editorial?
you must show your effort on the problem first
I tried first for 1 hour and then read it but I didn't get it
anyway if you can please help with this.
3 cases to handle dp
so which part you don't understand?
why do we need 3 parameters instead of 2 parameters like classical knapsack ( Subset) I knew we need more parameters but how this 3 parameters handle it?
you show no effort in solving the problem
I suggest leaving the question unsolved until you get something
keep asking general question won't do any good
