Given a directed graph with V nodes and E edges. If there is an edge from u to v then u depends on v. Find out the sum of dependencies for every node. Duplicate edges should be counted as separate edges.

**Example 1:**

Input:V=4 E=4 Edges={ {0,2},{0,3},{1,3},{2,3} }Output:4Explanation:For the graph in diagram, A depends on C and D i.e. 2, B depends on D i.e. 1, C depends on D i.e. 1 and D depends on none. Hence answer -> 0 + 1 + 1 + 2 = 4

**Example 2:**

**Input:**
V=4
E=3
Edges={ {0,3},{0,2},{0,1} }
**Output:**
3
**Explanation:**
The sum of dependencies=3+0+0+0=3.

**Your Task:**

You don't need to read input or print anything.Your task is to complete the function **sumOfDependencies()** which takes the adj (Adjacency list) and V (Number of nodes)as input parameters and returns the total sum of dependencies of all nodes.

**Expected Time Complexity:**O(V)

**Expected Auxillary Space:**O(1)

**Constraints:**

1<=V,E<=150

0<= Edges[i][0],Edges[i][1] <= V-1
