The knapsack problem is one of the famous and important problems that come under the greedy method. As this problem is solved using a greedy method, this problem is one of the optimization problems, more precisely a combinatorial optimization.. The optimization problem needs to find an optimal solution and hence no exhaustive …

WebGreedy approach: In Greedy approach, we calculate the ratio of profit/weight, and accordingly, we will select the item. The item with the highest ratio would be selected first. There are basically three approaches to solve the problem: The first approach is to select the item based on the maximum profit.
