You have a graph ofnnodes. You are given an integernand an arrayedgeswhereedges[i] = [ai, bi]indicates that there is an edge betweenaiandbiin the graph. Returnthe number of connected components in the graph. Example 1: Input: n = 5, edges = [[0,1],[1,2],[3,4]] Output: 2...
Summary: We present two improved versions of Tarjan's algorithm for the detection of strongly connected components in a directed graph. Our new algorithms handle sparse graphs and graphs with many trivial components (containing only one node) more economically than Tarjan's original algorithm. As an...

A strongly connected component is the portion of a directed graph in which there is a path from each vertex to another vertex. It is applicable only on a directed graph. For example: Let us take the graph below. Initial graph The strongly connected components of the above graph are: ...
