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).

**Constraints:**

1 ≤ V ≤ 10^{5}

1 ≤ E ≤ 10^{5}

0 ≤ u, v ≤ N-1
