    856 - Score of Parentheses.

    Medium

    Given a balanced parentheses string s, return the score of the string.

    The score of a balanced parentheses string is based on the following rule:

    • "()" has score 1.

    • AB has score A + B, where A and B are balanced parentheses strings.

    • (A) has score 2 * A, where A is a balanced parentheses string.

    Example 1:

    Input: s = "()"

    Output: 1

    Example 2:

    Input: s = "(())"

    Output: 2

    Example 3:

    Input: s = "()()"

    Output: 2

    Constraints:

    • 2 <= s.length <= 50

    • s consists of only '(' and ')'.

    • s is a balanced parentheses string.
