Puzzling Through Older Problems

Kenneth Fisher shares a couple of interview puzzles:

The year is 2004. You’re taking a tech test as an interview for a SQL development job. They have a page in their application that displays up to 20 rows of information. They need a piece of code that will return the rows from a given page. Oh, and it may not always be 20 rows per page. You need to write a piece of code where they can pass in a page number and page size and get back results. So for example, if the page size is 20 and the page is 3 then you need to return back rows 41 to 60.

The answers aren’t on the page, but then again, that’s the point of a puzzle.
