Input: startTime = [1,2,3,3], endTime = [3,4,5,6], profit = [50,10,40,70] Output: 120 Explanation: The subset chosen is the first and fourth job. We should add the number of boxes added multiplied by the units per box to our answer (ans), and decrease T by the same number of boxes. Therefore, sort the customers according to the increasing order of demand so that maximum number of customers can be satisfied. You can choose any boxes to put on the truck as long as the number of boxes does not exceed truckSize. They can still re-publish the post if they are not suspended. Yash is a Full Stack web developer. Can alternatively describe it as O(n) for storage of n elements. This means a variable has two types associated with it at any specific point of code location: a declaration type and a narrowed type.
