Force buckle -- design cycle queue (problem solution)
This problem needs to implement a circular queue, so before that, we need to know the concept and structure of queue
Queue: a special linear table that can only be inserted at one end and deleted at the other end. It has the characteristics of first in first out, then in and then out Delete one end of the queue Enter the queue: the end of t ...

Two way bfs -- dimension reduction attack on the rearrangement of the nine palaces
What is bidirectional bfs?
Ordinary bfs traverses downward from one vertex, while bidirectional bfs traverses downward and upward from the two endpoints in turn when the end point is known, until the number of layers overlaps with the previous traversal, the answer comes out. It is clear that a two-way bfs needs to meet a necessary cond ...

STL container: dual end queue deque and priority queue priority_queue
Double ended queue deque
deque is a double ended queue, which can be inserted at the head and tail, or deleted at the head and tail. Its advantage is that it combines the advantages of vector and list, but realizes random access and header plug deletion. When the space is not enough and needs to be expanded, it does not need to be as compl ...

Data structure - linear structure: Queue ["Queue" corresponds to a subset of array operations;]
2, Queue
The operation can only be performed at one end of the list (the operation can be performed at the other end of the list) through the specified order of the list (the operation can be performed at the other end of the list).
Queue: a First In First Out linear table, called FIFO for short. The end allowed to be inserted is the ...

Chapter 4 stack and queue
Chapter 4 stack and queue
A stack is a linear table that is restricted to insert and delete operations only at the end of the table. We call the end that allows insertion and deletion as the top of the stack, the other end as the bottom of the stack, and the stack without any data elements as an empty stack. Stack is also called last in first ...
