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

False
>>> matched(“a)*(?”)
False
>>> matched(“((jkl)78(A)&l(8(dd(FJI:),):)?)”)
True
