Decode the Coding Interview in Python: Real-World Examples

Module 1: Introduction & Setup

⏳ 1 hour

• Topics: Overview of coding interviews, Python setup, big-O notation, and expectations.

• Hands-on: Analyze the efficiency of simple Python snippets using time complexity.

Module 2: Arrays & Strings

⏳ 3 hours
