That's neat - I wonder what the limits in terms of tractable computation
the approach has on modern hardware.
In regards to the 'char 0 of' something being empty, I decided not to do
it that way for clarity mainly. In developing LCB (which is an attempt
to make a strict version of LCS, essentially) many questions have come
up (as I'm sure Peter could comment on at length) as to what one should
really think of as being 'correct'.
On the one hand LCS is very forgiving as it makes (what some might say)
are 'sensible' defaults in edge-case conditions; on the other hand LCB
is not at all forgiving as it expects you to be precise. There is a
balance to be struck here in terms of making things 'easy' (which is, to
be fair, a rather ill-defined property in this context)...
Too lax and it is too easy to make hard to detect logic errors in code,
too strict and it makes writing the code more difficult and frustrating
and verbose.
