A programmer can use the in operator to check whether a value is equal to any element of a sequence. For example, the expression 'of' in ['a', 'list', 'of', 'words'] is true because 'of' is the third element of the list.

The not in operator works similarly, except that it checks whether the value is not equal to every element of a sequence. 'word' not in ['a', 'list', 'of', 'words'] would be true, for instance, because 'word' (without the "s") is different from all of the strings in the list.

These operators, however, work slightly differently when applied to strings, again because Python has no character type. An expression like 'word' in 'words' does not check whether 'word' is equal to a character in 'words' (which would be false), but whether 'word' is a substring of 'words' (which is true).

Fill in the placeholders so that the actual outputs match the expected outputs.
