WebJul 19, 2024 · Method 1 – without using STL: The idea is to use Greedy Approach. Below are the steps: Find the ratio value/weight for each item and sort the item on the basis of this ratio. Choose the item with the highest ratio and add them until we can’t add the next item as a whole. In the end, add the next item as much as we can.

WebGreedy algorithms tend to be made up of five components. These components include: A candidate set from which a solution is created. A selection function, which picks the best candidate that will be added to the solution. A feasibility function. This is used to determine whether a candidate can be used to contribute to a solution. WebMar 21, 2024 · Greedy is an algorithmic paradigm that builds up a solution piece by piece, always choosing the next piece that offers the most obvious and immediate benefit. So the problems where choosing locally optimal also leads to global solution are the best fit for Greedy. For example consider the Fractional Knapsack Problem.
