About this MCQ
This Medium Data Structures MCQ checks one syllabus fact.
The question is: “Identify the correct definition of Priority queue.”
The accepted answer is B. An abstract data structure where each element has a priority, and elements are served according to that priority rather than arrival order.. Priority queue refers to an abstract data structure where each element has a priority, and elements are served according to that priority rather than arrival order.
