Data Structure and Algorithm/leetcode/lintcode

Build StatusSlack StatusChat on Slack

Introduction

This work is some notes of learning and practicing data structures and algorithm.

  1. Part I is some brief introduction of basic data structures and algorithm, such as, linked lists, stack, queues, trees, sorting and etc.
  2. Part II is the analysis and summary of programming problems, and most of the programming problems come from https://leetcode.com/, http://www.lintcode.com/, http://www.geeksforgeeks.org/, http://hihocoder.com/, https://www.topcoder.com/.
  3. Part III is the appendix of resume and other supplements.

This project is hosted on https://github.com/billryan/algorithm-exercise and rendered by Gitbook. You can star the repository on the GitHub to keep track of updates. Another choice is to subscribe channel #github_commit via Slack https://ds-algo.slack.com/messages/github_commit/. RSS feed is under development.

Feel free to access http://slackin4ds-algo.herokuapp.com for Slack invite automation.
