Given a string s of '(' , ')' and lowercase English characters.

\n\n

Your task is to remove the minimum number of parentheses ( '(' or ')', in any positions ) so that the resulting parentheses string is valid and return any valid string.

\n\n

Formally, a parentheses string is valid if and only if:

\n\n\n\n

 

\n

Example 1:

\n\n
\nInput: s = "lee(t(c)o)de)"\nOutput: "lee(t(c)o)de"\nExplanation: "lee(t(co)de)" , "lee(t(c)ode)" would also be accepted.\n
\n\n

Example 2:

\n\n
\nInput: s = "a)b(c)d"\nOutput: "ab(c)d"\n
\n\n

Example 3:

\n\n
\nInput: s = "))(("\nOutput: ""\nExplanation: An empty string is also valid.\n
\n\n
