About the Book
Starting Leetcode can be a challenge. Most Data Structures and Algorithms (DSA) books 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, you still feel like you are not getting anywhere. In the other camp are oversimplified books: they feel great to read, but when it comes time to actually implement what you have learned, you are left clueless.
This book bridges that divide. This book has all you need to know to transition from knowing Python to confidently solving coding interview problems. I wrote this because it is the book I wish I had when I started - and that is why I am making it free! I hope you will find this book 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- Pure Python: No pseudocode or outdated languages.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.
