Strongly connected component (Tarjans's Algo)
Hard Accuracy: 44.27% Submissions: 1504 Points: 8

Given a Directed Graph with V vertices and E edges, Find the members of strongly connected components in the graph.

 

Example 1:

Input:

Output:
0 1 2,3,4,
Explanation:

We can clearly see that there are 3 Strongly
Connected Components in the Graph as mentioned
in the Output.

Example 2:

Input:

Output:
0 1 2,
Explanation:
All of the nodes are connected to each other.
So, there's only one SCC as shown.

 

Your Task:
You don't need to read input or print anything. Your task is to complete the function tarjans() which takes the number of vertices V and adjacency list of the graph as input parameters and returns a list of list of integers denoting the members of strongly connected components in the given graph.
Note: A single strongly connected component must be represented in the form of a list if integers sorted in the ascending order. The resulting list should consist of a list of all SCCs which must be sorted in a way such that a lexicographically smaller list of integers appears first. 

 

Expected Time Complexity: O(V + E).
Expected Auxiliary Space: O(V).
