In my previous post, I shared some source code to sort one million 8-digit numbers in 1MB of RAM as an answer to this Stack Overflow question. The program works, but I didn’t explain how, leaving it as a kind of puzzle for the reader. I had promised to explain it in a followup post, and in the meantime, there’s been a flurry of discussion in the comments and on Reddit. In particular, commenter Ben

Earlier this week, this Stack Overflow question was featured on Reddit under /r/programming. Apparently, it was once a Google interview question – or at least, a variation of one: You have a computer with 1M of RAM and no other local storage. You must use it to accept 1 million 8-digit decimal numbers over a TCP connection, sort them, and then send the sorted list out over another TCP connection.

IntroFuzzy search algorithms (also known as similarity search algorithms) are a basis of spell-checkers and full-fledged search engines like Google or Yandex. For example, these algorithms are used to provide the "Did you mean ..." function. In this article I'll discuss the following concepts, methods and algorithms: Levenshtein distance Damerau-Levenshtein distance Bitap algorithm with modificati

The Archive of Interesting Code is an (ambitious) effort on my part to research, intuit, and code up every interesting algorithm and data structure ever invented. In doing so, I hope both to learn the mathematical techniques that power these technologies and to improve my skills as a programmer. The examples on this site are in a variety of languages. I generally prefer to use C++ for algorithms,
