OK, the gauntlet has been thrown. http://asksasha.com/strrev.c
coded in 25 minutes. When compiled with -O3 gives me this on my laptop: bash-4.1$ time ./strrev /usr/share/dict/words > /dev/null real 0m0.055s user 0m0.053s sys 0m0.002s my /usr/share/dict/words can be downloaded from here: http://asksasha.com/words when compiled with default flags (with gcc 4.4.5) I got 0.09 s of real time Levi, beat this in Haskell. Barry, Dale, beat this in Java. Anybody else, beat this in your language of choice including C - I do not claim that my implementation is the best. Post your development time. If you think the rules are not fair, feel free to protest. For those who cannot read C, the program reads the strings from the file given by the first argument delimited by \n, reverses each and prints the result to stdout. To compile it: gcc -O3 -o strrev strrev.c Yes, and for those who are too smart for their own good - your program must dump out the correct result when you print to stdout instead of redirecting to /dev/null, and it must work correctly on any file that has lines shorter than 512 bytes. If the line is longer than that it can truncate the string, but must not crash. -- Sasha Pachev Fast Running Blog. http://fastrunningblog.com Run. Blog. Improve.
