WebJun 6, 2024 · In function count_edges, declare a variable count=0 which is to return the count of the edges. Traverse the list using a loop until we reach the last vertice and add the value of count with graph_list [i].size () and store it back to the count variable. After we reach the last vertice, divide the value of count by two, and print the result. Web0. We can find the number of edges from the following observations: The degree of a vertex v counts the number of times v appears as the endpoint of an edge. If we sum …
WebSep 7, 2024 · Naive Approach: The simplest approach is to generate all possible paths from each node of the given graph and store the count of edges occurring in these paths by a HashMap.Finally, print the frequencies of each edge. Time Complexity: O(N 2) Auxiliary Space: O(N) Efficient Approach: To optimize the above approach, the following … WebThe sum of the vertex degree values is twice the number of edges, because each of the edges has been counted from both ends. In your case $6$ vertices of degree $4$ mean there are $(6\times 4) / 2 = 12$ edges.
