Symmetric difference: Difference between revisions

=={{header|Quackery}}==

<lang Quackery> [ $ "rosetta/bitwisesets.qky" loadfile ] now!

( i.e. using the Quackery code for sets at

http://rosettacode.org/wiki/Set#Indexed_Bitmaps )

set{ John Bob Mary Serena }set is A ( --> { )

set{ Jim Mary John Bob }set is B ( --> { )

say "A \ B is " A B difference echoset cr

say "B \ A is " B A difference echoset cr

say "(A \ B) U (B \ A) is "

A B difference B A difference union echoset cr

say "Using built-in symmetric difference: "

A B symmdiff echoset cr</lang>

{{out}}

<pre>A \ B is { Serena }

B \ A is { Jim }

(A \ B) U (B \ A) is { Jim Serena }

Using built-in symmetric difference: { Jim Serena }</pre>
