Try it yourself:
| @1 |
setSymDifference([1, 2, 3, 4], [3, 4, 5, 6])
|
|
| @2 |
setSymDifference([[1, 2], [3, 4]], [[3, 4], [5, 6]])
|
setSymDifference(A, B) returns values that belong to exactly one of two sets. Shared values are removed.
For {1,2,3} and {2,3,4}, the symmetric difference is {1,4}. Use setDifference for one directional exclusion and setIntersect to identify what was shared.
Duplicates do not change set membership. Normalize sources with setDistinct, and use setUnion if both unique and shared values should be retained.
Start with one of the editable examples above, then replace its arguments with your own values. Keeping the function on a separate calculator line makes the input and result easy to compare. For a longer workflow, assign the result to a variable or reference that line in the next expression.
Check the shown signature before adding optional arguments, and use the related-function links to compare operations with similar purposes.
