Rightward drift is a problem that is encountered in a reference-based implementation of a queue.

Question

Quizplus · Accepted Answer

Rightward drift is a problem typically associated with array-based implementations of a queue, where elements are shifted towards the end of the array over time as elements are added and removed, potentially leading to inefficient use of space or the need to shift elements back towards the front of the array. Reference-based implementations (e.g., linked lists) do not suffer from this issue since elements are dynamically allocated and deallocated without needing to shift positions in a physical array.
