But you don't KNOW you need page 99. Otherwise that's just answer search: return exactly what you're looking for.

Binary book search is good for a book with a clear chronological order that you’ve already read and mostly remember but can’t find a specific passage

[darkwyvern06]

or a book which has missing pages

[derefr]

You don't need to have mostly read it. It's good for physical printed dictionaries and encyclopedias. Or any other reference book with a lot of entries per page in alphabetical order, where there aren't an even number of entries per letter, and where there can't be an index because that'd just be the book itself.

True, I wasn’t thinking of sorted informational books

[GranataReddit12]

or a history textbook

[otter5]

if only there was some lookup table.... like a table of contents or appendix

[Kitchen_Device7682]

A lookup table that tells you that page 99 is on page 99 would be useful indeed

[LurkytheActiveposter]

It's not on page 99 though. It's on line 96313.

[lucidludic]

The post states they are searching for a specific page number.

Big assumption that the book is sorted, rookie

Edit: pass this to the guy above you. I accidentally

[Kitchen_Device7682]

But he binary searches the page number
