Welcome to this repo! It contains all my notes for leetcode challenges.

• Tag Collections

Here I will pick the most classic leetcode questions for each tag.

• Solutions

Besides knowing how to solve the problem, it is even more important that you know how you can come up with such a solution, what characteristics of the challenge inspire you.

In my solution, I share the codes, the complexity analysis, together with my thoughts.

• Algorithm templates

Here are the best templates I've found easy to use for some algo like binary search, sorting, etc.

After understanding the idea of the algo, the templates can minimize the chances to have bugs in your code.

• History of leetcode contests

I started to take part in the weekly contests on Leetcode at the beginning of 2022 April, when I have solved around 250 challenges.

Few people share such private data, unless they're already good at it. I choose do so, because I'm accepting the fact that I'm just a common man, not that smart. It is your hard work and sweat that make you worth of study and respect.

I hope I can prove I can make huge progress via my efforts.
