WebAug 22, 2011 · The real question might be: Can you change any recursive algorithm to require only constant space, potentially by way of using tail recursion? The answer, of course, is maybe. Typically, recursive functions that use tree recursion (where recursive calls branch into multiple deeper recursive calls) might be hard to transform this way.
