Can you explain the compare-and-swap algorithm?
Sure! The compare-and-swap (CAS) algorithm is an atomic operation used in concurrent programming to achieve synchronization.
How does it work in practice?
In practice, CAS checks if a variable has a specific value and, if so, updates it to a new value. It's often used in lock-free data structures.
What are some advantages of using compare-and-swap?
Some advantages include reduced contention and improved performance in multi-threaded environments, as it avoids traditional locking.
Can you give me a real-world example of where it's used?
Certainly! CAS is commonly used in implementing concurrent data structures like stacks and queues, where multiple threads may access them simultaneously.
