WebThe objects correspond to mathematical abstractions called vertices (also called nodes or points) and each of the related pairs of vertices is called an edge (also called link or line ). [1] Typically, a graph is depicted in diagrammatic form as a set of dots or circles for the vertices, joined by lines or curves for the edges. WebTree (data structure) This unsorted tree has non-unique values and is non-binary, because the number of children varies from one (e.g. node 9) to three (node 7). The root node, at the top, has no parent. In computer science, a tree is a widely used abstract data type that represents a hierarchical tree structure with a set of connected nodes ...
