Two Sum looks simple. That’s why most people underestimate it. But the real value isn’t the answer — it’s the thinking process behind it: how you optimize, reason about complexity, and choose data structures.
This is where real algorithm skill starts.

The animations and script are made in the same style as my infrastructure videos — like networking, databases, and servers — and the narration for those parts is read by AI. The coding section, though, is still my own voice 😄
