1. General topic On the Go board, if there are chess pieces in the four directions of a certain coordinate, up, down, left, and right, then ans + 1. According to the number of input chess pieces, find the number of ans. 2. Problem-solving ideas The question mentions that if the program does not end, […]

Unity vertices, uv, image maps, and mesh
Mesh is the triangles that make up a 3D object. The mesh is composed of triangles composed of vertices. The size of the triangles does not need to be the same and is determined by the position between the vertices. A mesh can be one or more faces. The origin of the texture is in […]
(16) In the graph, the algorithm idea of finding the shortest path from a vertex to other vertices, Dijkstra (Dijkstra), Bellman-Ford algorithm, Floyd (Floyd) algorithm
Directory algorithm thinking Implementation steps 1. Dijkstra algorithm execution steps: 2. Bellman-Ford algorithm execution steps 3. Floyd algorithm execution steps For example, in the figure above, find the shortest path from V1 to every other vertex. There are 3 common algorithms for finding the shortest path, namely Dijkstra (Dijkstra), Bellman-Ford algorithm, and Floyd (Floyd) algorithm, […]
[Data algorithm and structure] The unweighted directed graph G is stored in an adjacency list, find the in-degree and out-degree of each vertex in the graph G, find the vertex with the largest out-degree in the graph G and output the vertex number, calculate the number of vertices with an out-degree of 0 in the graph G, and judge whether there is an edge <i,j> in the graph G
Title Question:?Try to write an algorithm assuming that the unweighted directed graph G is stored in an adjacency list, and design and implement algorithms to solve the following problems. Find the in-degree of each vertex in graph G. Find the out-degree of each vertex in graph G. Find the vertex with the largest out-degree in […]
