Jul 02, 2013 · Then we just use bwd() on the current edge to find an edge that pointed to this node, then rinse and repeat k times. Indegree In a similar manner to outdegree, all we need to do is count the edges that point to the current node label. Take for example the graph: We can easily find the first incoming edge by using backward().

A regular coordinated chart should likewise fulfill the more grounded condition that the indegree and outdegree of every vertex are equivalent to one another. Answer and Explanation: More technically, the indegree of a node u is |{(x,u): (x,u) E}|, where the vertical bar notation |S| gives the number of elements in set S. Similarly, the outdegree of u is given by |{(u,x): (u,x) E}|. A node with positive outdegree but no indegree is called a source. A node with positive indegree but no outdegree is called a sink.

Type Parameters: V - The type of data to associate with each vertex. E - The type of data, if any, to store inside each edge. Some graphs do not need to store any extra information in each edge, in which case you can supply a meaningless type for E (such as Void) and can avoid passing any extra information when adding edges to the graph.
