markdown Today I want to say I wrote three LeetCode questions - [52. N-Queens II](https://leetcode.com/problems/n-queens-ii/submissions/1913376856) [ Time taken: 25 m 45 s ] - [22. Generate Parentheses](https://leetcode.com/problems/generate-parentheses/submissions/1913468059) [ Time taken: 7 m 15 s ] db - [79. Word Search](https://leetcode.com/problems/word-search/submissions/1913484901) [ Time taken: 18 m 54 s ] I'm surprised that I have an idea immediately when writing N-Queen II. My LeetCode's `Top Interview 150` list almost done, there are 15 questions left. I will start to read some system design and DDIA. I realize my English skill is improved. I'm happy about it.
