Webknapsack contains items 1 and 3 (total: $46). As we shall see in Chapter 8, neither version of this problem is likely to have a polynomial-time algorithm. However, using dynamic programming they can both be solved in O(nW) time, which is reasonable when W is small, but is not polynomial since the input size is proportional to logWrather than W. WebJan 7, 2024 · For example, N = 4, W = 10 and the weights and values of items are weights = [6, 1, 5, 3] and values = [3, 6, 1, 4]. Then the best way to fill the knapsack is to choose items with weight 6, 1 and 3. The total value of knapsack = 3 + 6 + 4 = 13. Input Format: The first line contains a single integer 'T' representing the number of test cases.
