示例：使用字典的方式构建有向图，并搜索图中的路径。图很容易通过列表和词典来构造。比如说，这有一张简单的图：A->BA->CA->DB->EC->DC->FD->BD->EE->F->DF->GG->E这个图有6个节点(A-G)和8个弧。它可以通过下面的Python数据结构来表示：graph={A:[B,C,D],B:[E],C:[D,F],D:[B,E,G],E:[],F:[D,G]G:[E]}代码#找到一条从start到end的路径deffindPath(graph,start,end,path=[]):path=path+[start]ifstart==end:returnpathfornodeing... 2024-05-15013.29 KB2页
