–Use queue data structure which can retrieve the visited nodes in order. (FIFO) –You have to use BFS to solve this assignment. Solve a problem: Queue –Hyeonah's tomato farm has a large warehouse for storing tomatoes –The tomatoes are placed in a box (a grid-shaped box) as shown ...
Data Structure Graph: strong connectivity 摘要:如果为undirected graph就是dfs或者bfs,如果都能visit则为连通O(V+E).如果为directed graph就先dfs或者bfs,再reverse direct,再dfs或者bfs,如果两次都连通则为strong connecthttp://www.geeksforgeek... 阅读全文 ...
(a)What is Algorithm and Data Structure? Algorithm: Algorithms are basically methods or recipes for solving various problems. To write a program to solve some problems, we first need to know a suitable algorithm. 算法导论:非形式的说,算法就是任何良定义的计算过程,该过程取某个值或者值的集合作为...
In BFS algorithm, Queue data structure is used. In DFS algorithm, Stack data structure is used.51) What are the applications of Graph data structure?The graph has the following applications:Graphs are used in circuit networks where points of connection are drawn as vertices and component wires ...
