|---|---|---|---|---|---|---|
| of | 1 | 2 | 3 | 4 | ||
| and | 3 | 4 | 5 | 6 | ||
| is | 1 | 2 | ||||
Implementation:
- loop over setA
- does setB has element of setA
- if yes, return the element
Symmetric
The symmetric difference is the union of the two asymmetric difference
- asymmetric diff SetA to SetB
- asymmetric diff SetB to SetA
