| Subject: | More whitespace in examples could show "picture" of operations |
The following two examples show how reformatting could make a visual
presentation to better visualize the operations, allowing ASCII Art to
create a "picture" of the various Venn Diagram operations.
Some examples of the various set differences:
set or difference value
$a (a b c d e)
$b ( c d e f g)
$c ( e f g h i)
$a->difference($b) (a b)
$a->symmetric_difference($b) (a b f g)
$a->unique($b) (a b f g)
$b->difference($a) ( f g)
$b->symmetric_difference($a) (a b f g)
$b->unique($a) (a b f g)
$a->difference($b, $c) (a b)
$a->symmetric_difference($b, $c) (a b e h i)
$a->unique($b, $c) (a b h i)
