Wow. My last fumblings where something along the lines of:
-l $_=pop;0while+print,s+.+$&*111%100if/../+eg,chop
which I couldn't get to work.
Perhaps as post-mortem regarding that discussion about the tiebreaker,
I was wondering how you guys got rid of the while. I guessed there
wasn't a while involved because I thought "there's got to be a pop, a
print, certainly an s with e and g". If figured the best solution
didn't had a while in it since in mine that uses 7 strokes with 6 \w's.
The above solution also uses 7 strokes for the "same" purpose
(side-effects aside, which is the killer), but the tie-breaker is
lower.
The 1.11%10 bit made me giggle for some reason.
Regarding my "one step" solution, the secret can be computed as:
Op(i=1..digits, C(i, digits)*digit[i])
where Op(a,b) := (0, 1..9, 1..9, ...)[a+b] and C(i, j) := j!/i!/(j-i)!
(or something like that, I can't think straight right now). This lead
to a horribly long solution that doesn't even pass the test program :-)
Thanks guys, my first tournament ever was lots of fun!
