What are the differences between a stack and a queue?
What will be an ideal response?
A queue data structure allows nodes to be removed only from the head of the queue and inserted only at the tail of the queue. A queue is referred to as a first-in, first-out (FIFO) data structure. A stack data structure allows nodes to be added to the stack and removed from the stack only at the top. A stack is referred to as a last-in, firstout (LIFO) data structure.
