Talk:Symmetric difference
The symmetric difference should give one list which is the union of the two differences of the lists. The Perl example shows two lists. --Mwn3d 23:19, 2 December 2009 (UTC)
- I agree with your statement about what “symmetric difference” means.
- All of the current examples produce two sets.
- The task as written tends to the two-lists interpretation.
Conclusion: Either the task should be renamed, or the task description should be clarified and the examples revised. --Kevin Reid 02:02, 3 December 2009 (UTC)
