in reply to Generating a Pattern

Here's mine:

#!/usr/local/bin/perl @a=split(//,"1"); #easier to make test strings this way. :) for (1..10) { print "@a\n"; @b=(); $a=join("",@a); while ( $a =~ /((.)\2*/cg ) { push (@b, (length $1, $2)); } @a=@b }
500 iterations of this took 1.15 seconds. 10 iterations running 1..35 took 18.73 seconds. For reference, I'm running this on an Ultrasparc-5.

    That is more or less identical to my regex solution. Very nice, though.
