1 stack is an associative container, another "container class" obtained by simply modifying the interface of a linear class of deque, which is often summed up as a connector (adapter) rather than a container (container). Stack cannot traverse, so

In many cases, our program, before performing the next step, will need to wait for the execution of the previous one, which is most evident in the asynchronous operation, or in the program that uses the message loop mechanism to communicate. An

Heap The heap is an array object of a completely binary tree. Each layer of the tree is full, except that the last layer may be Zuozi (from the beginning of a node). Given the node I, it is easy to compute the location of the parent and child nodes.
