Of course there is the brute force solution, O(n), where you use a nested for-loop and calculate every single sum, but the DP solution is O(n), and is less lines of code. Once unpublished, this post will become invisible to the public and only accessible to seanpgallivan. If we sort the engineers by efficiency, we can iterate downward through the engineers while evaluating the combined speed (totalSpeed) of the ideal group. You signed in with another tab or window. 157 more parts. Find the time at which there are maximum guests in the party. I could solve this by brute force but I am not able to understand its editorial. I tried putting print statements all over the place, but the only thing I came to is that 1 too many elements get added to the list - hence, the last if statement (to drop the last added element), but it made no difference whatsoever, so it's probably wrong. Largest Submatrix With Rearrangements, LeetCode 1751. With you every step of your journey. 2nd query: nums = [2,3,4], k = 2 since 2 XOR 3 XOR 4 XOR 2 = 7.

For this problem, we don't need to actually sort every element, which would take longer than O(N) time. You are given a 2D array boxTypes, where boxTypes[i] = [numberOfBoxesi, numberOfUnitsPerBoxi]: You are also given an integer truckSize, which is the maximum number of boxes that can be put on the truck. You signed in with another tab or window. Instead, we can create another array of arrays (ord) with both stats combined into one array, then sort it based on the efficiency. (Which makes sense, because some of the lists there included 250K+ elements.). Problem List. Find XOR Sum of All Pairs Bitwise AND, LeetCode 1836.
