Then we can iterate through B and at each step, we should add as many of the boxes as we can, until we reach the truck size (T). Only one valid answer exists. Now, check if the maximum difference is between ith and maximum element, store it in variable diff. Since the index numbers between speed and efficiency correspond to each other, we shouldn't just sort efficiency, however. What is the purpose of this D-shaped ring at the base of the tongue on my hiking boots? Simplest Python solution. If we sort the engineers by efficiency, we can iterate downward through the engineers while evaluating the combined speed (totalSpeed) of the ideal group.

Sliding Window Maximum (LeetCode) Given an array nums, there is a sliding window of size k which is moving from the very left of the array to . Rest of the customer cannot purchase the remaining rice, as their demand is greater than available amount. We use Stacks so that "if there is a tie for most frequent element, the element closest to the top of the stack is removed and returned.". An Efficient Solution is to use sorting n O(nLogn) time. Approach: In order to meet the demand of maximum number of customers we must start with the customer with minimum demand so that we have maximum amount of rice left to satisfy remaining customers.
