Subject: Re: [SOLUTION] Ruby Quiz #14 LCD Numbers ( solution #2 )

256 bytes.

Shrik again from 264 bytes. New idea again.
I agree, at this point, this program is not readable at all.

If you like a readable version, 
please check my solution #1 
( maybe it is not readable either :-) )

What I did is I try to make a as small as possible program for the solution.
I have fun for this solution is about its size, 
not the readable / maintenace / performance ... etc.

There are many ways to play, I just try to take other way and have fun.
(Of couse, if this is my job, I would not solve as it right now :-) )

OK, anyway, like it or not; here is the 256 bytes program.
( Not the gmail wrap line, it is this mailing list wrap my code.
So this time, I list the line number as [n], 
if the program wrapped, join the line together yourself,
sometime the line is wrap when a blank character to separate "word", 
so when join line, you may need add a blank character)

[1] s=(s=$*.index"-s")?$*.slice!(s,2)[1].to_i: 2
[2] d,="\21\265\22H\245\10-\0\23".unpack"B*"
[3] f=" "
[4] o=48
[5] 5.times{|x|((t=x%2==0)?1:s).times{puts
$*[0].split('').map{|z|u=d[7*z.to_i,7]
[6] t ?u[x/2*3]>o ?f*s+f+f:f+"-"*s+f:(u[h=x*4/3]>o
?f:"|")+f*s+(u[h+1]>o ?f:"|")}*f}}
