Stack: First in, last out
Queue and stack traversal data speed
Queue: It is traversed based on the address pointer, and it can be traversed from the head or the tail, but it cannot be traversed at the same time. There is no need to open up space, because the data structure is not affected during the traversal process, so the traversal speed is faster
Stack: Data can only be fetched from the top, that is to say, the data that enters the bottom of the stack first needs to be traversed through the entire stack before it can be taken out. When traversing data, microdata needs to open up temporary space to maintain the consistency of the data before traversing
