"WebApr 3, 2024 · An efficient solution is to use the Greedy approach. The basic idea of the greedy approach is to calculate the ratio profit/weight for each item and sort the item on the basis of this ratio. Then take the item with the highest ratio and add them as much as we can (can be the whole element or a fraction of it). " - Greedy approach in daa

WebDivide and Conquer algorithm consists of a dispute using the following three steps. Divide the original problem into a set of subproblems. Conquer: Solve every subproblem individually, recursively. Combine: Put together the solutions of the subproblems to get the solution to the whole problem. Generally, we can follow the divide-and-conquer ... WebThe greedy approach suggests constructing a solution through a sequence of steps, each expanding a partially constructed solution obtained so far, until a complete solution to the problem is reached. On each step and this is the central point of this technique.
