Title: This question requires you to realize an exclusive online map of the ladder race. After the team members enter their school location and venue location, the map should recommend two routes: one is the fastest route to reach; One is the shortest route. The topic ensures that there is at least one reachable route on the map for any query ...

Linear table summary Linear table is the most basic, simplest and most commonly used data structure.A linear table is a finite sequence of n data elements with the same characteristics. Pioneer element: if element A is in front of element B, it is called the precursor element of B Successor element: if element B is after element a, it ...

1, Linear meter interface specification Linear tables generally need to implement the following interfaces: #pragma once #include <iostream> template<class T> class linearList { public: virtual ~linearList() {}; virtual bool empty() = 0; virtual int size() const = 0; virtual T& get(int index) const = 0; virtual int in ...

1, Purpose and significance of type extraction 1. Type extraction is the purpose (1) A typical application is to distinguish whether T is a source generated type POD or a user-defined type in the template function (2)POD,Plain Old Data, is simply understood as the basic types inherited from C by C + +, such as int, double, etc (3) The e ...

In the previous chapter, we talked about 10 common data structures, and then we talked about 10 common algorithms. Address of the previous chapter: Foundation compaction: Basic data structure and algorithm (I) , you can have a look if you don't know much. 10 common algorithms The content of data structure research is how to organize t ...

Research and reproduction of time A * algorithm based on neural network prediction 1. Thesis reading and information extraction 1.1 construction of road network topology Weighted directed graph The intersection is the vertex of the graph, and the road is the edge of the graph. The topology information needs to be stored: [node type] N ...

The basis of data structure from the perspective of python array concept An array is an ordered set of finite variables of the same type. Sequential storage in memory can realize logical sequential table. python mainly uses lists and tuples, which are essentially the encapsulation of arrays. basic operation #Initialization list my_list = ...

preface Finally started the algorithm... Recursion is really abstract. Without basic principles, it is like metaphysics... #1, What problems can be solved by recursion!

chart 1, Figure basic introduction 1. Why is there a map We learned linear tables and trees earlierThe linear table is limited to the relationship between a direct precursor and a direct successorThe tree can only have one direct precursor, that is, the parent nodeWhen we need to represent many to many relationships, we use graphs here. 2. ...
