What is the basic difference between stack and queue??

Please help me i am unable to find the difference.

How do you differentiate a stack a

Answer 1

Imagine a stack of paper. The last piece put into the stack is on the top, so it is the first one to come out. This is LIFO. Adding a piece of paper is called "pushing", and removing a piece of paper is called "popping".

Imagine a queue at the store. The first person in line is the first person to get out of line. This is FIFO. A person getting into line is "enqueued", and a person getting out of line is "dequeued".
