golang 使用github.com/scylladb/go-set/strset求交并集

A := strset.NewWithSize(0)
A.Add("a","b","c","d")
B := strset.NewWithSize(0)
B.Add("a","d","e","c")

unionSet :=strset.NewWithSize(0) //交集
intersectionSet :=strset.NewWithSize(0) //并集

intersectionSet = A.Copy()
intersectionSet.Add(B.List()...)

if A.HasAny(B.List()...) || B.HasAny(A.List()...){
	unionSet  = A.Copy()
	A.Remove(B.List()...)
	unionSet .Remove(A.List()...)
}

fmt.Println("交集：",unionSet )
fmt.Println("并集：",intersectionSet)
