adjacency matrix or incidence matrix) until we find no more node that hasn’t been visited and connected with current node, then we go back to last node. Repeat above procedures until all nodes have been visited.
Preface BFS（Breath-First Search，⼴度优先搜索）与DFS（Depth-First Search，深度优先搜索）是两种针对树与图数据结构的遍历或搜索算法，在树与图相关算法的考察中是⾮常常见的两种解题思路。Definition of DFS and BFS DFS的:Depth-first search (DFS) is an algorithm for traversing or searching tree or ...

Adjacency Matrix 邻接矩阵是表示一个图的常用存储表示。它用两个数组分别存储数据元素(顶点)的信息和数据元素之间的关系(边或弧)的信息。阶为n的图G的邻接矩阵A是n*n的。将G的顶点标签为v_1,v_2,...,v_n。若(v_i,v_j) \in E(G),A_{ij}=1,否则A_{ij}=0。
Dijkstra's algorithm solves the single-source shortest-paths problem in edge-weighted digraphs with nonnegative weights using extra space proportional to V and time proportional to E log V (in the worst case). 2. BFS Find shortest path 2.1 1091.Shortest Path in Binary Matrix Loading.....
