In a Queue ADT, which operation removes an element from the Queue?

Question

BlackTom AI · Accepted Answer

The question asks which operation removes an element from the Queue in a Queue ADT.
Option a: remove. While some data structures use a remove operation, in the context of a Queue ADT the typical removal operation is known as dequeue or serve in this wording. Therefore remove is not the standard term here, making this choice less accurate for a classic queue.
Option b: pull. This term is not standard in queue terminology. Pulling suggests drawing an item from somewhere, but it is not the conventional queue operation name for removal, so this is incorrect.
Option c: serve. In many teaching contexts and implementations, the operation that takes the element at the front of the queue and removes it is called serve (or dequeue). This is the operation that actually removes an element from the queue, aligning with the expected behavior.
Option d: pop. Pop is typically associated with stacks, where the top element is removed. Since a queue removes from the front (and sometimes from the back in certain variants), pop is not the standard queue removal operation, so this is incorrect here.
