Explanation:
Advance the pointers in such a way that the fast pointer advances two nodes at a time and slow pointer advances one node at a time and check to see if at any given instant of time if the fast pointer points to slow pointer or if the fast pointer’s ‘next’ points to the slow pointer. This is applicable for smaller lists.

Опрос

Keep one node as head and traverse another temp node till end to check if its ‘next points to head
Have fast and slow pointers with fast pointer advancing two nodes at a time
Cannot determine, you have to pre-define if the list contains cycles
Circular linked list itself represents a cycle. So no new cycles cannot be generated

API Architecture Styles

Choosing the Right API Style Today

APIs come in many flavors, each suited for different needs. SOAP, though reliable for enterprise apps, feels outdated with its XML complexity. RESTful APIs are still the go-to for simplicity and wide adoption, but they can suffer from over- or under-fetching data.

GraphQL is the modern favorite, perfect for getting exactly the data you need—great for front-end flexibility. gRPC shines in high-performance, microservices-heavy environments, while WebSockets handle real-time, low-latency communication brilliantly. Finally, Webhooks are ideal for event-driven applications with asynchronous needs.

In today’s world, GraphQL or RESTful APIs often dominate, but your choice should depend on your app’s specific requirements.
