About this blog

Purpose

I started writing this blog as a memo for my coding interview preparation process.
At the mean while, I hope readers can find useful contents in this blog, either
you are preparing for coding interview the same as me, or just hoping to sharp your
data structures and algorithms.

Approaches

• I will use Leetcode as my main source of coding questions and answering templates.
• I will try to complete selected questions by tags in Leetcode. For each question,
  they will be approached in a various aspects:
  • Problem set
  • Problem set analysis
  • Thinking process
  • Brutal force / First solution
  • Improvements
  • Answer analysis: time/space complexities
  • Take aways: conclusions, templates, programming related takeaways such as the
    usage of a given data structure.
• I will draw a knowledge graph that can represent the structure of all the
  problems and their underlying data structure and algorithms that we have processed
  so that readers can get a general idea of the big picture of data structures and algorithms.

  Pre-requisites

• Basic knowledge of Python. We will use Python3 and I will also try to cover some
  basic programming knowledge about Python
• Leetcode access. You can register it for free.
• Basic knowledge of data structures like array, strings, hashmap and etc. I won’t
  assume any advanced knowledge of complicated data structure such as tree and graph.
  Knowledge of algorithms are not required as learning them together is the main purpose
  of this blog.

Discussion

As I will try my best effort to make my post as accurate as possible, I would also
appreciate your feedback for any questions and improvements. You can use the discussion
section under each question to interact with me and other readers.

Q&A

• When will I update the blog?
  • I will try to update it on a daily basis but there will for sure be gaps.
• What’s your practicing order for Leetcode tags?
  • I will post another follow up blog to talk about my plans for practicing with
    Leetcode.
• Will system designs be discussed?
  • Yes but it will come after the data structure and algorithms.
