class Question{

/* m is the number of elements in arr1[]

            }

        }

        while (i < n)

    }

    public static void main(String args[])

    {

        int arr1[] = {1,3,8};

        int arr2[] = {2,3,5,10};

  int arr2[] = {4,6};

        int m = arr1.length;

        int n = arr2.length;

  int o = arr3.length;

        printIntersection(arr1,arr2,m,n);

  printUnion(arr1,arr2,m,n);

relativeComplement(arr1,arr2,m,n)

    }

}

A\B is same as A-B both are called as Rlative Complement.

please follow the above program for other.
