About the Book
When I first started doing LeetCode, I was completely lost. I tried searching for good resources, but found that most Data Structures and Algorithms books seemed to fall into two frustrating camps. In one camp are books written like academic journals, where intuition gets buried under dense theoretical derivations. After a month of reading, I still felt like I was not getting anywhere. In the other camp are oversimplified books: they feel great to read, but when it comes time to actually implement what I have learned, I was left clueless.
I wrote this book to bridge this divide and help you transition from knowing Python to confidently cracking coding interview problems! This is the book I wish I had when I was first starting out with LeetCode. I hope you find it helpful!
Key Features:
- Pure Python: No pseudocode or outdated languages.
- Prerequisite: The only prerequisite is a basic understanding of Python.
- DSA Concepts: Complex DSA concepts are explained through relatable analogies rather than dry math.
- Practical Implementation: Quickly dive into the code to implement DSA concepts and solve coding interview problems.
- Coding Interview Patterns: Master the important LeetCode patterns to ace your next coding interview.
And Most Importantly,
- No AI. Every explanation is carefully crafted, and every diagram is manually rendered with LaTeX.
