Write a function f a,b that takes two strings and returns a string containing only the characters found in both the strings in the order of a.
Trees have roots and children. Arbitrary graphs, on the other hand… I think "origin" and "neighbors" would be more appropriate. Once you perform a dfs or bfsthat graph is "ruined".
You won't be able to reset all nodes to the unvisited state. Well, you could do it manually, since Node. But that's nasty too.
Instead, I suggest that dfs and bfs keep a HashSet of visited nodes. Once the traversal is done, just discard the set. That value is never used. The name suggests that it would return a single node, but it doesn't.
Also, by returning the entire array, and the original of the array rather than a copy, you would be letting the caller alter the graph's connections in unapproved ways. Better to offer ways to iterate through all neighbours and to fetch a specific neighbour.
The Node constructor says: You should test against vertices. If the capacity is exceeded, you should't print to System. Throw an exception instead, so that the caller can decide how to handle it.
Better yet, use an expandable data structure so that you don't have to deal with capacity limits. Those arrays seem to serve the same purpose, redundantly. You can't reuse the code for anything else, since the System.
It would be better to implement an Iterator so that the caller can decide what to do with each node. Therefore, they should be implemented in two classes with a shared interface. The breadth-first iterator is a pretty straightforward translation of your original code, with the main difference being that the iterator is now responsible for keeping track of which vertices have been visited.
Instead, you'll have to rewrite it as an iterative solution using an explicit stack, which makes the code more complicated. Alternatively, if you abandon the idea of making an Iterator and use the visitor pattern instead, then you could keep the same recursive code structure.
With the original code, which always printed its output to System. Now, you can do anything you want with the results, so it is possible to write proper unit tests.The APOC library consists of many (about ) procedures and functions to help with many different tasks in areas like data integration, graph algorithms or data conversion.
In computer science, tree traversal (also known as tree search) is a form of graph traversal and refers to the process of visiting (checking and/or updating) each node in a tree data structure, exactly srmvision.com traversals are classified by the order in which the nodes are visited.
The following algorithms are described for a binary tree, but they may be generalized to other trees as well. Program to create a graph and use Deapth First Search(DFS) and Breadth First Search(BFS) Traversal..

And so, the only possible way for BFS (or DFS) to find the shortest path in a weighted graph is to search the entire graph and keep recording the minimum distance from source to the destination vertex.
