Please help with the following Discrete mathematics assignment in SQL.

Using either SML, SQLite or Forth, or any combination of these languages, write at least one program to satisfy the following:

Note the set operations above that produce sets, except #2 and #5, which returns a booleans. Note that for #7, the power set function takes as input any single set, which in this case is the result of the union of x and y.

Set Op Description Algorithm Code Algorithm Source Explanation Attribution Correct Output Set Operation 1. Equal (x,y) - boolean 2. Union (x,y) 3. Intersection (x,y) 4. Difference (x,y) 5. Subset (x,y) - boolean 6. Cross product (x,y) 7. PowerSet (Union(x,y))
