LCD display acm

[RexLee]

The problem is: http://uva.onlinejudge.org/index.php?option=com_onlinejudge&Itemid=8&page=show_problem&problem=647

But the way I solved it isn't efficient.

So I found a solution on the web: http://code.google.com/p/acm-uva-ufrgs/source/browse/trunk/%20acm-uva-ufrgs/Problem%20Set%20Volumes/Volume+VII/706.c?r=2

But I don't understand the conversation table in the source code.

LC displays are made of 7 segments, like this

 

 

so, for each digit you have to display, you need to know how to "draw" the 7-segments version of it

you can do this by just storing the on/off state of each segment for each digit, or you can do it like it's done in the solution you found and store what to draw in the place where the segment is

 

edit:

it's shortly explained in the code too, am i missing the part that you actually didn't understand?

Thanks I get it now.
