Reply to comment by PlaugeofRage in TIL after a seizure left him paralyzed except for his left eyelid, Jean-Dominique Bauby (1952-1997) wrote the bestselling book "The Diving Bell and the Butterfly" by blinking to select each letter as an assistant recited the alphabet to him. by chumloadio

Honestly my vague memories of first year programming were suggesting a binary search (first half of the alphabet or second, first half of your subsequent selection or second) but a grid is much faster.

Trees are much faster, they only need to store what's actually there.

A matrix only works better when its full.

Of course its way easier to understand
