<s>[INST] We can assign a score to a string consisting of parentheses based on the following rules:
() -> 1 point
(()) -> 2 points
(()()) -> 2 points
((())) -> 3 points
We can also assign a score to each state to maintain the balance of the parentheses. 
For example, after processing the first parenthesis in the string "(()())", we get score 1 and state 1 (denoted as (1, 1)).
After processing the second parenthesis in the string "(()())", we get score 2 and state 2 (denoted as (2, 2)).
After processing the third parenthesis in the string "(()())", we get score 1 and state 1 (denoted as (1, 1)).
After processing the fourth parenthesis in the string "(()())", we get score 2 and state 4 (denoted as (2, 4)).
After processing the fifth parenthesis in the string "(()())", we get score 1 and state 3 (denoted as (1, 3)).
After processing the sixth parenthesis in the string "(()())", we get score 1 and state 2 (denoted as (1, 2)).
After processing the seventh parenthesis in the string "(()())", we get score 1 and state 1 (denoted as (1, 1)).
After processing the eighth parenthesis in the string "(()())", we get score 0 and state 0 (denoted as (0, 0)).
Approach this problem as a string matching problem to find the maximum score. We can use a stack to keep track of the state.

Here is my implementation in C++:
