from typing import Iterable

print("Example:")

# These "asserts" are used for self-checking and not for an auto-testing
assert list(compress([

assert list(compress([1, 1, 1, 1, 2, 2, 2, 1, 1, 1])) == [1, 2, 1]
assert list(compress([7, 7])) == [7]
assert list(compress([])) == []
assert list(compress([1, 2, 3, 4])) == [1, 2, 3, 4]
assert list(compress([9, 9, 9, 9, 9, 9, 9])) == [9]
