Directions (Q91–95): For a knapsack problem, P and W are the profits and weights of a set of 7 items:
P = {9, 5, 2, 7, 6, 16, 9}
W = {2, 5, 6, 11, 1, 9, 3}
If a new item (P = 5, W = 2) is added, giving 8 items, and the capacity is 25, then the time of fractional knapsack in this case is ______
Pick an option to check yourself, or open the answer below.
Show answer & explanation
Correct answer: C. O(24)
Explanation
Fractional knapsack is dominated by sorting the items by ratio, O(n log n). With n = 8: 8 × log₂8 = 24.More Data Structures and Algorithms questions
