Answer this

Question

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

Answer 1

def matched(s):
brackets_counter = 0
i = 0
while brackets_counter >= 0 and i < len(s):
if s[i] == '(':
brackets_counter += 1
elif s[i] == ')':
brackets_counter -= 1
i += 1
if brackets_counter == 0:
return True
else:
return False
