There is a bi-directional graph withnvertices, where each vertex is labeled from0ton - 1(inclusive). The edges in the graph are represented as a 2D integer arrayedges, where eachedges[i] = [ui, vi]denotes a bi-directional edge between vertexuiand vertexvi. Every vertex pair is connecte...

Another corner case is the path might contain multiple slashes'/'together, such as"/home//foo/". In this case, you should ignore redundant slashes and return"/home/foo". 核心在于编写一个以'/'为分隔符的split函数 以及用进出栈来保存最简路径。
Consider a directed graph, with nodes labelled0, 1, ..., n-1. In this graph, each edge is either red or blue, and there could be self-edges or parallel edges. Each[i, j]inred_edgesdenotes a red directed edge from nodeito nodej. Similarly, each[i, j]inblue_edgesdenotes a blue...
