LeetCode: Delete and Earn Posted on August 5, 2018July 26, 2020 by braindenny Delete and Earn Similar Problems: CheatSheet: Leetcode For Code Interview CheatSheet: Common Code Problems & Follow-ups Tag: #dynamicprogramming Given an array nums of integers, you can perform operations on the array. In each operation, you pick any nums[i] and delete it to earn nums[i] points. After, you must delete every element equal to nums[i] – 1 or nums[i] + 1. You start with 0 points. Return the maximum number of points you can earn by applying such operations. Example 1: Input: nums = [3, 4, 2] Output: 6 Explanation: Delete 4 to earn 4 points, consequently 3 is also deleted. Then, delete 2 to earn 2 points. 6 total points are earned. Example 2: Input: nums = [2, 2, 3, 3, 3, 4] Output: 9 Explanation: Delete 3 to earn 3 points, deleting both 2's and the 4. Then, delete 3 again to earn 3 points, and 3 again to earn 3 points. 9 total points are earned. Note: The length of nums is at most 20000. Each element nums[i] is an integer in the range [1, 10000].
