We just have a loop for W within a loop of N =>O (NW) Implementation : Here comes the obligatory implementation code in Java class Knapsack { public static void main(String[] args) throws Exception { int val[] = {10, 40, 30, 50}; int wt[] = {5, 4, 6, 3}; int W = 10; System.out.println(knapsack(val, wt, W)); } public static int knapsack(int val[], int wt[], int W) { int N = wt.length; // Get the total number of items.

So, it is kind of intuitive that the rest of the row will just be the same value too since we are unable to add in any other item for that extra weight that we have got. Solution : 1) Now, lets start filling in the array row-wise. The weight of the first item is 5. For the remaining weight 0, are we able to accommodate Item 1? Simply put, is there any value at all in the row above for the given weight) The calculation goes like so : 1) Take the max value for the same weight without this item previous row, same weight = 0 => V[item-1][weight] 2) Take the value of the current item + value that we could accommodate with the remaining weight Value of current item + value in previous row with weight 4 (total weight until now (4) - weight of the current item (4)) => val[item-1] + V[item-1][weight-wt[item-1]] Max among the two is 40 (0 and 40) 3) The next and the most important event happens at column 9 and row 2.
