:::*The join_sets() function should return a set that contains all values from both sets:::*The match_sets() function should return a set that contains all values found in both sets:::*The diff_sets() function should return a set that contains all values which are not shared between both sets:::*All three functions should accept '''two arguments''' both are sets:::*The script should show the exact output as the samples:::*The script should contain no errors
