Forexample,create_set ([ 1, 2; 3, 4; 4, 2 ])⇒ [ 1, 2, 3, 4 ]union (x, y)Function FileReturn the set of elements that are in either of the sets x and y. For example,union ([ 1, 2, 4 ], [ 2, 3, 5 ])⇒ [ 1, 2, 3, 4, 5 ]intersection (x, y)Return the set of elements that are in both sets x and y. For example,intersection ([ 1, 2, 3 ], [ 2, 3, 5 ])⇒ [ 2, 3 ]Function Filecomplement (x, y)Return the elements of set y that are not in set x. For example,complement ([ 1, 2, 3 ], [ 2, 3, 5 ])⇒ 5Function File
