Find the Symmetric Difference
The mathematical term symmetric difference (△ or ⊕) of two sets is the set
of elements which are in either of the two sets but not in both. For example,
for sets A = {1, 2, 3} and B = {2, 3, 4}, A △ B = {1, 4}.
Symmetric difference is a binary operation, which means it operates on only two
elements. So to evaluate an expression involving symmetric differences among
three elements (A △ B △ C), you must complete one operation at a time. Thus,
for sets A and B above, and C = {2, 3},
A △ B △ C = (A △ B) △ C = {1, 4} △ {2, 3} = {1, 2, 3, 4}.
