Grokking Algorithms
An illustrated guide to algorithms and data structures — 2nd edition.
Why this one
The illustrated approach earns its title — the drawings do real work, not decoration. Binary search, big-O, and the graph chapters land faster than in denser texts because every idea gets a picture before the code.
Standouts so far
- Big-O by feel — the runtime chapter builds intuition before notation.
- Graphs — BFS/Dijkstra explained with worked, drawn examples.
- Dynamic programming — the grid framing finally made it click.
More notes as I finish the back half.
