You can save 6 more bytes, by replacing your s/// command with H;G, as explained here

With echo -n absolutely nothing gets passed to sed, but sed can't start without input by design. Check this meta link to see that echo|sed is the accepted way to start sed for challenges invoking a no input rule.

@seshoumara echo -n | sed 's:a\?:&a:g' and got no output. It would be the same as sed 's::a:' which wouldn't match anything.

| Feb 3, 2017 at 15:54 | comment | added | Riley | @seshoumara I don't think that'll match anything when the pattern space is empty, so it'll never make the first replacement. | |

Hi, how about s:a\?:&a:g? It is 1 byte less and doubles the pattern size per iteration as well.
