Sword pointing to offer data structure and algorithm

Brief introduction to offer data structure and algorithm resources:

Data structure and offer series, described in Python.

Break down the complex issues step by step to make them easier to understand.

The program is completely handwritten, and the idea of ​​each step is explained.
