one function named get_ok_items, which will be responsible for determining the allowed items in a persons carryon and personal bags. The function should have three parameters, all of which will be sets of items (strings). The first set represents the carryon bag contents, the seconds represents the personal bag items, and the third represents the restricted items. The function should return the set of allowed elements. For instance, the code:

restricted = {'knife', 'water', 'razor'}

carryon = {'laptop', 'water', 'clothes'}

personal = {'mints', 'knife', 'keys'}

result = get_ok_items(carryon, personal, restricted)

print(result)

Should print

{'mints', 'keys', 'clothes', 'laptop'}
