But the good news is that many problems that are NP-complete in theory, are quite easy in the real world! Then, from largest remaining number to smallest, it finds the container where adding that number makes the smallest difference to the optimal average. Nearly 80 percent of all containers in the cloud run on AWS today. Given a string s consisting of items as "*" and closed compartments as an open and close "|", an array of starting indices startIndices, and an array of ending indices endIndices, determine the number of items in closed compartments within the substring between the two indices, inclusive. After completing the above steps, print the value of ans . An item is represented as an asterisk (*1 = ascii decimal 42) A compartment is represented as a pair of pipes that may or may not have items between them ('1' = ascii decimal 124). You signed in with another tab or window. First Fit:When processing the next item, scan the previous bins in order and place the item in the first bin that fits. First Fit decreasing produces the best result for the sample input because items are sorted first.First Fit Decreasing can also be implemented in O(n Log n) time using Self-Balancing Binary Search Trees.This article is contributed by Dheeraj Gupta.
