Question

Which of the following is true about the queue container?

a) Faster than list
b) FIFO, LIFO, Priority are implementations of the queue
c) Recommendation system is an implementation of priority queue
d) All of the above

Answer 1

The correct answer is 'b) FIFO, LIFO, Priority are implementations of the queue', as queues can be implemented in various ways, including FIFO, LIFO (stacks), and priority queues. Recommendation systems can use priority queues, but the statement regarding speed is not universally applicable.

Step-by-step explanation:

The correct answer to the question is 'b) FIFO, LIFO, Priority are implementations of the queue'. A queue is a data structure that organizes elements in a first-in, first-out (FIFO) manner. However, there are variations of queues that include last-in, first-out (LIFO) structures, commonly known as stacks, and priority queues that return elements based on their priority rather than the order they were added.

The statement 'c) Recommendation system is an implementation of priority queue' could be considered true in some cases, as recommendation systems can indeed use priority queues to manage and prioritize recommendations based on certain criteria.

As for 'a) Faster than list', this is not universally true and depends on the operations being performed and the data structure implementation. So, the most accurate option is 'b)'.
