English translation is in progress... Some articles are still in Chinese, but most are completed. Please star this repo. The full translation will eventually be finished. Enjoy.
These articles go over different kinds of Algorithmic Thinking. All are based on LeetCode problems. They contain not just the solution code for a problem, but also WHY the solution works and HOW you too can figure it out.
I don't like one-liners. They can be confusing. I like clear, easily understandable code.
The Gitbook has been deployed and will sync with this branch of the repo: https://labuladong.gitbook.io/algo-en/
If you would like to clone this repo, please use following command:
git clone --depth 1 --branch english https://github.com/labuladong/fucking-algorithm.gitThis command specifies the english branch and will limit the depth of the clone and get rid of the Git commit history, which can be faster to clone.
