ARTS Week 28


This week’s LeetCode problem is 347. Top K Frequent Elements

Given an integer array nums and an integer k, return the k most frequent elements. You may return the answer in any order.

First traverse the array once, and use Map to count the occurrences of each element. Then use the occurrences of different elements as the basis for sorting, maintain a small top heap of size k, and finally get the elements at the top of the heap.


This week’s Review is for the following article: Why don’t I have a blog?

  • “I’m not a good programmer”: the author believes that most of his skills are just beginner level and there is no need to share them.
  • “I don’t think it’s good CV building”: The author thinks that the average blog is not enough as a good resume building platform, if you only have a blog, maybe no one will visit.
