密码检测

        if (isdigit(c)) hasDigit = true;
        if (ispunct(c)) hasSymbol = true;
    }

    // Determine password strength
    if (length >= 12 && hasLower && hasUpper && hasDigit && hasSymbol) {
        return GREEN;  // Strong
    } else if (length >= 8 && ((hasUpper && hasLower) || (hasLower && hasDigit) || (hasUpper && hasDigit))) {
        return YELLOW;  // Medium
    } else {
        return RED;  // Weak
