There are no greedy algorithms for 0-1 Knapsack even though greedy works for Fractional Knapsack. This is because in 0-1 Knapsack you either take ALL of the item or you don't take the item at all, unlike in Fractional Knapsack where you can just take part of an item if your bag overflows. This is crucial.

WebSort the array in decreasing order using the value/weight ratio. Start taking the element having the maximum value/weight ratio. If the weight of the current item is less than the current knapsack capacity, add the whole item, or else add the portion of the item to the knapsack. Stop adding the elements when the capacity of the knapsack becomes 0. WebKnapsack Problem . The knapsack problem is one of the famous and important problems that come under the greedy method.
