How does the Google “Did you mean?” Algorithm work?
...th of words stored. There is no easy way to index Levenshtein distance for fast retrieval of near matches without calculating the Levenshtein distance some billions of times for every word queried. Levenshtein distance is therefore not of much use in this situation, at least not in the first stage,...

Comparing arrays in JUnit assertions, concise built-in way?
...es to JUnit's issue tracking system. Bear in mind, though, that 1) failing fast, in O(1), can be an advantage, 2) the assertion failure output should not be O(n). The JUnit issue tracking system is a better forum for further discussion.
