πŸš€ The Algorithm Mastery Series: From Fundamentals to 2026's Cutting Edge

A 10-Part Journey from Student to Professional Problem Solver

"In 2026, algorithms aren't just academic exercisesβ€”they're the invisible engines powering AI, securing quantum-resistant systems, and orchestrating global supply chains. This series takes you from 'Hello World' to solving tomorrow's hardest problems."


🎯 Why This Series Exists

The Gap:

What Universities Teach          What Industry Needs (2026)
─────────────────────           ─────────────────────────
β€’ Sorting algorithms            β€’ LLM optimization algorithms
β€’ Binary search                 β€’ Real-time recommendation engines
β€’ Graph traversal               β€’ Quantum-safe cryptography
β€’ Big-O notation               β€’ Autonomous system decision-making
β€’ Textbook problems            β€’ Billion-scale data processing
