In particular, X that I'm thinking about in particular is the Quick Sort algorithm.

There are currently 9 questions tagged quick-sort in 4 different languages: 1 in lisp, 4 in C++, 1 in C and 3 in Java. There are 5 others found in a search that are not tagged quick-sort.

A lot of the questions have more than just the sorting code in their question so maybe they deserve to stay. But I'm tempted to close some as duplicates for another since they asked about their implementation when really one of the other reviews on the duplicates could be applied. Though we're not reviewing their code, we have already reviewed code exactly like it.

What should we do about these questions? Should we start closing them as duplicates when there isn't anything substantially different about the code? Should we leave them be?
