[amp_mcq option1=”Stack, Queue” option2=”Queue, Stack” option3=”Priority Queue, Stack” option4=”Stack. Priority Queue” correct=”option1″]

The correct answer is: LIFO is a stack, while FIFO is a queue.

A stack is a data structure in which elements are added and removed from the top. The last element added to the stack is the first element removed, hence the acronym LIFO, which stands for Last In, First Out.

A queue is a data structure in which elements are added to the end and removed from the beginning. The first element added to the queue is the last element removed, hence the acronym FIFO, which stands for First In, First Out.

Priority queues are a type of data structure that stores elements with a priority associated with each element. The elements are then sorted by their priority, and the element with the highest priority is always the first element to be removed from the queue.

In conclusion, LIFO is a stack, while FIFO is a queue.
