Which HTTP methods are commonly used by RESTful services for resource state management?

Explanation:
In RESTful services, resource state is manipulated through HTTP methods that map to CRUD operations. GET retrieves a resource without changing it, serving as a safe read. POST creates a new resource under a collection or can trigger server-side actions, and it is not idempotent by default. PUT replaces or creates a resource at a known URI and is idempotent, meaning repeated calls have the same effect as a single one. PATCH applies a partial update to a resource, allowing you to modify only specific fields. DELETE removes a resource and is idempotent, so repeated deletions don’t change the outcome after the first. Together, these methods cover the typical lifecycle of a resource: read, create, update (full or partial), and delete. There are other HTTP methods like HEAD and OPTIONS, but they mainly handle metadata and discovery rather than changing resource state, so they aren’t part of the standard set used for state mutations.
