 Posted: Tue May 27, 2003 10:36 pm Post subject: Combinations... |
 |
|
I'm absolutely stumped on how to make every possible combination of
a string of numbers starting at 0 and ending at 255.
I'm trying to make a script which will make every combination of numbers
starting from 0|0|0 to 255|255|255. I have spent many hours thinking
about this and I just don't know how it is done. 
In other words, I need help on making a script that makes every
combination, such as 245|32|80 etc., all the way to 255|255|255.
Thanks in advance for any help!

Parse the string since it has "|" in it. Use IF @GREATER() to insure that
each is not greater than 255, if so, then take the number back down to
255.
Then for low end, IF @EQUAL(@SUBSTR(%%VAR,1,1),-), if so, then take
the number back up to 0.
Once done, put all 3 variables back into a string again.

I'm not sure I follow you entirely. 
Could you please explain further?
I really appreciate your help.

| Code: | %%FullVar = -0|256|23
INFO %%FullVar
Option Fieldsep,|
Parse "%%Var1;%%Var2;%%Var3",%%FullVar
If @greater(%%Var1,255)
%%Var1 = 255
ElsIf @equal(@substr(%%Var1,1,1),-)
%%Var1 = 0
End
If @greater(%%Var2,255)
%%Var2 = 255

The basic premis would be as follows
| Code: |
List create,1
%A = 0
%B = 0
%C = 0
%D = 0
list add,1,%A|%B|%C
repeat
If @equal(%D,1)
%A = @succ(%A)
end
list add,1,%A|%B|%C
repeat
If @equal(%D,1)
%B = @succ(%B)
end
list add,1,%A|%B|%C
repeat
If @equal(%D,1)
%C = @succ(%C)
end
%D = 1
list add,1,%A|%B|%C
until @equal(%C,255)
%C = 0
until @equal(%B,255)
%B = 0
until @equal(%A,255)
list savefile,c:\count.txt
shell open,c:\count.txt
end
|
%D is to make sure that "0" is used before @succ()
The problem here is that your list will run out of memory when %A gets to "3" or "4"
Maybe if you somehow played with it to get more than one set per line.
I think I read in a earlier post that a list has a maximum number of characters
Hope this helps get you started. |

Here is a visual example 
| Code: |
DIALOG CREATE,Test,-1,0,40,27
DIALOG ADD,text,TX,6,24,,,
DIALOG SHOW
%A = 0
%B = 0
%C = 0
%D = 0
dialog set,tx,%A|%B|%C
repeat
If @equal(%D,1)
%A = @succ(%A)
end
dialog set,tx,%A|%B|%C
repeat
If @equal(%D,1)
%B = @succ(%B)
end
dialog set,tx,%A|%B|%C
repeat
If @equal(%D,1)
%C = @succ(%C)
end
%D = 1
dialog set,tx,%A|%B|%C
rem ** remove the "REM" below to see it slower **
rem wait .001
%E = @event()
If %E
goto %E
end
until @equal(%C,255)
%C = 0
until @equal(%B,255)
%B = 0
until @equal(%A,255)
:close
end

he's looking for.

Hey FF
Why on Earth do you wanna make such a list?? You need a list of every darn IP address, or what 
Or are ya just trying to pass time in this snoozefest by figuring out how to do it?
Before you do that for real, try to do some simple math of combinations - we're talkin' several billion combinations -
I doubt it that you really wanna try to manage such a GB list in VDS

Well I just wanted to make a cool screensaver. 
I wanted it to blend from color to color but I don't know how to do that.
Anyway I wouldn't store a whole list like that, I would just go to the next
color shade/value.
BTW, it's the VDS way of stating an RGB color value.

Ahaaaa. So it was RGB values  he-he, in my mind it was IP addresses - that what ya get for posting
sooo early in the morning
Can't believe I missed the RGB connection - I'm currently trying to figure out how to calculate complementary colors
and split complementary colors for a given color.
Anyways good luck with you colorful screensaver

BTW Dr. Dread IP addresses have 4 octets in them not 3 like RGB
192.168.000.001 = IP address
128|128|128 = RGB colors
Anyway WAKE UP!

Yeah, I know. That's why I said the possible combinations would go into billions - with just three it'll only
be about 16 million.
And that's why that post was sooooo off on a tangent

Yup, just slapped myself - now I'm wide awake and ready for action...
Not much action around, though - still a snoozefest around here.

How can I extend the example above to work with four numbers like:
#|#|#|#
I appreciate any help.
