- 1$\begingroup$ You did not missing anything. Your implementation is better. Your analysis is correct. I recommend that you edit the question so that it is titled "Can the maximum single sell profit by divide and conquer be O(n) ?", explaining the O(n log n) algorithms known to you. Then write an answer with your algorithm. $\endgroup$喜欢算法和数学– 喜欢算法和数学2021-03-07 09:28:07 +00:00Commented Mar 7, 2021 at 9:28

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. complexity-theory), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
