LeetCode ProblemDelivering Boxes from Storage to Ports
You have the task of delivering some boxes from storage to their ports using only one ship. However, this ship has a limit on the number of boxes and the total weight that it can carry. You are given an array boxes, where boxes[i] = [portsi, weighti], and three integers portsCount, maxBoxes, and maxWeight. The boxes need to be delivered in the order they are given. The ship will follow these steps: The ship must end at storage after all the boxes have been delivered. Return the minimum number of trips the ship needs to make to deliver all boxes to their respective ports.
