:I read it to show that each generator produced by <code>tee()</code> holds on to its own dequeue (list with pop() and append()). When a new item is taken from the original iterable, it is appended separately into each one of the dequeues. Were they all to share one dequeue amongst themselves, that would be a shared storage. <code>popleft()</code> wouldn't be always called, but only when the ''leftmost'' of internal iterators pointing into internal list would get advanced.

Good morning, |

Can you please undo the double-space style changes that you made on the Sieve thread-based solution? I find that kind of spacing much harder to read. Also, my intention in writing that code was to demonstrate Racket's ability to express solutions in different paradigms as well as show how such different solutions are really doing the same thing. For this reason I would like to keep unnecessary optimizations at a very minimal level. It's therefore questionable that the changes that you made (stepping by 2x, explicit 3 in the beginning) are worth it. Whatever speedup you get as a result of changing the argument order is definitely not worth it for this goal. So please avoid such optimizations -- not turning this website into a festival of obscure optimizations like the language shootout thing is one of its most appealing properties. Thanks, --[[User:Elibarzilay|Elibarzilay]] ([[User talk:Elibarzilay|talk]]) 03:58, 6 November 2015 (UTC) |
