How can guessing the midpoint and discarding the half that can't hold the answer turn a linear hunt into logarithmic growth?
Short drills on what this video just taught. Write the code, run the checks, and reveal the answer only if you are stuck.
In the blind game you get 8 guesses, and each guess can check exactly one of the book's 448 pages. Your probability of winning is the fraction of the book your guesses can cover.
Compute that probability and assign it to odds.
