# 740. Delete and Earn LeetCode Solution | Easy Approach

Share:

Delete and Earn You are given an integer array `nums`. You want to maximize the number of points you get by performing the following operation any number of times:

• Pick any `nums[i]` and delete it to earn `nums[i]` points. Afterwards, you must delete every element equal to `nums[i] - 1` and every element equal to `nums[i] + 1`.

Return the maximum number of points you can earn by applying the above operation some number of times.

Example 1:

```Input: nums = [3,4,2]
Output: 6
Explanation: You can perform the following operations:
- Delete 4 to earn 4 points. Consequently, 3 is also deleted. nums = [2].
- Delete 2 to earn 2 points. nums = [].
You earn a total of 6 points.
```

Example 2:

```Input: nums = [2,2,3,3,3,4]
Output: 9
Explanation: You can perform the following operations:
- Delete a 3 to earn 3 points. All 2's and 4's are also deleted. nums = [3,3].
- Delete a 3 again to earn 3 points. nums = [3].
- Delete a 3 once more to earn 3 points. nums = [].
You earn a total of 9 points.```

Constraints:

• `1 <= nums.length <= 2 * 104`
• `1 <= nums[i] <= 104`
