Python's + operator can be used to concatenate two sequences of the same type.

For concatenating a sequence with itself, Python has the * operator. Given a sequence and an integer, the * computes the concatenation of that many copies of the sequence (or an empty sequence if the integer is nonpositive). For example, both ' ' * 8 and 8 * ' ' produce a string containing eight spaces. The preferred style is to write the number second.

Fill in the placeholders so that the actual outputs match the expected outputs. (As a reminder, strings inside of an single-quoted f-string must be written with double quotes.)
