Today I used real playing cards; a linen-finished standard deck. For any talk it’s nice to have a prop.
Now, I thought I understood the patience sort algorithm but until yesterday I’d never actually played it with real cards. I’ve been surprised by how much this physical dimension has developed my understanding.
I’ll be testing my new cards on some other sorting algorithms; I have high hopes. It would be good to find a similarly simple prop for linked data structures so I can balance trees, flip lists and walk graphs.
