Balanced Brackets Score

You have a string of brackets that includes '(', ')', '{', '}', '[' and ']'. Each bracket has a score based on its type: - '(': 1 - ')': 1 - '{': 2 - '}': 2 - '[': 3 - ']': 3 A sequence of brackets is deemed balanced if every opening bracket has a corresponding closing bracket in the correct order. Calculate the total score of a balanced string. Input: A single line string consisting of brackets (1 <= length <= 10^5). Output: An integer representing the score of the balanced brackets or -1 if the string is not balanced. Example: Input: {[()]} Output: 8 Explanation: The score is 2 (from '{') + 3 (from '[') + 1 (from '(') + 1 (from ')') + 3 (from ']') + 2 (from '}') = 8.
