You are given a string moves of length n consisting only of characters 'L', 'R', and '_'. The string represents your movement on a number line starting from the origin 0. In the ith move, you can choose one of the following directions: move to the left if moves[i] = 'L' or moves[i] = '_' move to the right if moves[i] = 'R' or moves[i] = '_' Return the *distance from the origin* of the *furthest* point you can get to after n moves. Example 1: Input: moves = L_RL__R Output: 3 Explanation: The furthest point we can reach from the origin 0 is point -3 through the following sequence of moves LLRLLLR. Example 2: Input: moves = R__LL Output: 5 Explanation: The furthest point we can reach from the origin 0 is point -5 through the following sequence of moves LRLLLLL. Example 3: Input: moves = _ Output: 7 Explanation: The furthest point we can reach from the origin 0 is point 7 through the following sequence of moves RRRRRRR.

Let's discuss the system design of your existing Salesforce integration with a Java backend. Could you please elaborate on the architecture, including specific details about data flow, integration patterns, and technologies used? For example, walk me through a scenario where a new account is created in Salesforce, and how that information propagates to your Java backend system. What mechanisms are in place for real-time updates versus batch processing? How do you handle data transformations and ensure data integrity across both systems? What are the key considerations for scalability, security, and fault tolerance in your design? Finally, describe the monitoring and alerting mechanisms you have implemented to ensure the integration is running smoothly and to quickly identify and address any issues that may arise. Provide details on the error handling strategies employed to prevent data loss or corruption in the event of failures.
