I've been quite entertained by the whole thread all weekend- it's been my diversion from wrestling with getting a new little computer to talk to various data acq devices using little C snippets to do the direct talking and wrapping Perl around it to make it faster to code up and modify. Fortunately I have most of it wired up and set for remote access, so I could work from the comfort of my couch much of the time. I'm remembering how much C I've forgotten...

The algorithm that surprises me the most is the recursive, in that you didn't end up with a lot of stack overhead slowing it down too much or hanging it up-- even just pushing return addresses on the stack and no data it's going to get large for your datasets. Once you showed the manual swaps, I was sure iterative was going to be the answer.

Most of what I thought the reversing algorithm had going for it was a) simple to code, b) sure to work without debugging, and c) you can probably fit it in about 20 bytes of code if you get sent back to 1983.
