Rest of the customer cannot purchase the remaining rice, as their demand is greater than available amount. 1), Solution: Maximum Score From Removing Substrings (ver. Maximum Value at a Given Index in a Bounded Array, LeetCode 1803. You may assume that each input would have exactly one solution, and you may not use the same element twice. This doesn't pass the same 7 test cases that are failing for OP. We want to find all the subsequences of the array consisting of exactly \ (m\) elements. Check if Binary String Has at Most One Segment of Ones, LeetCode 1785. Leetcode Problem #164 ( Hard ): Maximum Gap Description: ( Jump to: Solution Idea || Code: JavaScript | Python | Java | C++) Given an integer array nums, return the maximum difference between two successive elements in its sorted form. Therefore, sort the customers according to the increasing order of demand so that maximum number of customers can be satisfied. Quality answers are upvoted over time, mostly by future visitors gaining insight from your explanations. Two Sum 2. If you choose a job that ends at time X you will be able to start another job that starts at time X. 4th query: nums = [0], k = 3 since 0 XOR 3 = 3.

We are going to solve the problem using Priority Queue or Heap Data structure ( Max Heap ). Note that the implementation doesnt create a single sorted list of all events, rather it individually sorts arr[] and dep[] arrays, and then uses merge process of merge sort to process them together as a single sorted array. A bucket sort involves creating an array (buckets) in which the elements represent buckets that cover the spread of the numbers to be sorted. Examples: Constraints: 1 <= <= k <= n <= 10^5 speed.length == n efficiency.length == n 1 <= speed [i] <= 10^5 Once suspended, seanpgallivan will not be able to comment or publish posts until their suspension is removed.
