How does Arc help with memory management in Rust?

Arc allows multiple threads to own a value without needing to copy it, managing memory safely and efficiently.

Can you give me an example of using Arc in a Rust program?

Sure! Here's a simple example: you can wrap a value in Arc and share it across threads using the Arc::new() function.

What are the performance implications of using Arc?

Using Arc incurs some overhead due to atomic operations for reference counting, but it provides safe concurrent access.
