I need some working snippets on C++ code regarding breadth/depth first searches. Also, in the links below, when using the term tree, is it in reference to a binary tree or more specefically a red and black tree? Or is this a more abstract tree of sorts? Does anyone have a link to working code for these searches…along with constructing the tree?
Tree seems to refer to some sort of constuct with in the “graph”? I believe this is some sort of math I have not taken yet.
The tree in question is the thing they’re searching. It’s kinda hard to understand search algorithms without knowing what it is they are searching through.
A tree is a type of graph. A graph is a series of nodes (which presumably represent some data) with connections between certain nodes. A tree is a graph where the connections between nodes form a hierarchy. For any given node in the graph, it has exactly one “parent” that points to it, and it points to zero or more child nodes. And the nodes cannot form circles; a parent cannot point to a child who points to that parent.
Basically, like branches on a tree.
