Known Bug

Say: Required books: ABCDEFG

Actual books: CDEFG

When scanning C, both A and C will be labeled as false.

However, A is labeled false because it's missing, while C is labeled false because we found it and don't want to display it again. Those should not be categorized into the same.

Maybe establish another flag to distinguish the two.

When scanning D, B and D are labeled false.

HOWEVER

The next book on the screen is still D. Somehow.

The most recent commit solved this issue by checking every time and seeing if there are consecutive falses. This should have solved the problem, but I am unsure if it will lead to other issues. Since the 'false' flag can be set in two ways. If one book is found before it is supposed to be, as I stated, both the current position and the found book will be labeled as false... Thinking about that, if a book is labeled as false, what does it mean? Is it possible that I falsely skip a book?

The answer to this question is below:

If we are going from left to right and have found a false, the only reason the book is labeled 'false' is because this book has already been found. Since we are going from left to right, it is not possible to label a future book as 'false' the reason that the book is not found. Thus, it is not possible to skip it falsely. Since the fact that the book must be found before being labeled as false, it is right just to skip it and switch the label back to true.

I think that makes sense. I need to try it in real life and see if any special cases poped up.
