# symdiff

symdiff(s1,s2...)

Construct the symmetric difference of elements in the passed in sets or arrays. Maintains order with arrays.

## Examples

``````julia> s1 = Set("Hello");
julia> s2 = Set("World");

julia> symdiff(s1,s2)
Set{Char}({'d','e','H','r','W'})``````
``````julia> symdiff(sin(10), 1, 0:20)

The `symdiff` function takes in multiple sets or arrays and returns the symmetric difference of their elements. The symmetric difference is the set of elements that are present in one of the sets or arrays but not in both. The order of elements is maintained when using arrays.

Note that `symdiff` works with both sets and arrays, providing flexibility in its usage.
