> In a particularly egregious example of this, when I was interviewing for my second job out of college, I was asked to come up with an algorithm to eventually sink a submarine with unknown (but integral) position and velocity that was somewhere on a number line. (Spoiler alert: to solve this problem, you need to know how to enumerate the rationals.) Once again, zero lines of code. Once a new employee in a company posted this problem for discussion, claiming that the wording is intentionally changed to make it unsearchable, and the year was 2008. So I'm really interested how this wording came here - was the task popular enough to make it to the Web afterwards or is Emma's knowledge traceable to that employee through a chain of interested people? Or is there some other explanation?
