%%%%
+`(^|\b)%
0$%'¶$%`1
11!`\d+
Explanation
%%%%
Replace the empty (non-existent) input with %%%%
.
+`(^|\b)%
0$%'¶$%`1
On the first run of this stage, it will match ^%
and essentially replace the text %%%%
with the two lines 0%%%
and 1%%%
. The stage will loop until the output stops changing. On the second run, it will match \b%
(since digits count as word characters and %
doesn't), and replace the groups by duplicating them and adding 0
to one copy and 1
to the other: 0%%%
becomes the lines 00%%
and 01%%
(and the same sort of thing for 1%%%
). Through this loop all 16 bitstrings will be produced, linefeed separated.
11!`\d+
The first 11 matches of \d+
(a run of at least 1 digit) are retrieved. The matches are output in a linefeed-separated list.
