Answer: d. should be lowercase.

Explanation:

ID attributes are case sensitive for the most part - DOM and Java Script - which means that the ID attribute does not always have to be lowercase.

It can be uppercase as well. ID attributes can also start with a number and as of HTML 5 can start with a special character as well. Finally, the ID attribute must always be unique within each document.

Suppose we are given an arbitrary digraph G = (V, E) that may or may not be a DAG. Modify the topological ordering algorithm so

lianna [129]

Answer:

Check the explanation

Explanation:

We can utilize the above algorithm with a little in modification. If in each of the iteration, we discover a node with no inward edges, then we we’re expected succeed in creating a topological ordering.

If in a number of iteration, it becomes apparent that each of the node has a minimum of one inward edge, then there must be a presence of cycle in the graph.

So our algorithm in finding the cycle is this: continually follow an edge into the node we’re presently at (which is by choosing the first one on the adjacency list of inward edges to decrease the running time).

Since the entire node has an inward edge, we can do this continually or constantly until we revisit a node v for the first time.

The set of nodes that we will come across among these two successive visits is a cycle (which is traversed in the reverse direction).
