Knapsack greedy algorithm c++

Web2. Well, if it's 'fractional knapsack' (i.e. you can take fractions of the items) then it's easy: The items are (as price, weight pairs) [ (10, 3), (7, 2), (12, 4), (13, 3), (6, 13), (20, 8)] Intuitively, … WebFeb 6, 2024 · You used C++ map where "key" is the ratio of value per weight and the "value" is the item's id (the position of the item in the original order). So, what if two items have same value per weight? In that case, the map will only keep the one that comes later. This will potentially damage your solution.
