Write a program that prints the numbers from 1 to 100. But for multiples of three print “Fizz” instead of the number and for the multiples of five print “Buzz”. For numbers which are multiples of both three and five print “FizzBuzz”. Details: Your solution should be runnable and demonstrate the output. Focus on clean, readable code. Consider edge cases and error handling (though not strictly required for this basic version). Provide a brief explanation of your approach and any assumptions you made. Example: 1 2 Fizz 4 Buzz Fizz 7 8 Fizz Buzz 11 Fizz 13 14 FizzBuzz ... Variations (optional, for a more challenging exercise): Allow the user to input the upper limit of the range (instead of always going to 100). Allow the user to input the numbers to use for Fizz and Buzz (instead of always using 3 and 5). Allow the user to input the words to use for Fizz and Buzz (instead of always using Fizz and Buzz). Handle invalid inputs gracefully. This question assesses a candidate's basic programming skills, understanding of loops and conditional statements, and ability to write clean, understandable code. The variations allow for exploring error handling, input validation, and more flexible program design.

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.
