Write a function matched(s) that takes as input a string s and checks if the brackets "(" and ")" in s are matched: that is, every "(" has a matching ")" after it and every ")" has a matching "(" before it.

Your function should ignore all other symbols that appear in s.

Your function should return True if s has matched brackets and False if it does not.

Here are some examples to show how your function should work.

>>> matched("zb%78") True >>> matched("(7)(a") False >>> matched("a)*(?") False >>> matched("((jkl)78(A)&l(8(dd(FJI:),):)?)") True
