Web25 jul. 2024 · Pre-order traversal checks through the path from the root node to a leaf node before traveling down other paths following the order of parent, left, right. In the above example, the algorithm will ... A node is a structure which may contain data and connections to other nodes, sometimes called edges or links. Each node in a tree has zero or more child nodes, which are below it in the tree (by convention, trees are drawn with descendants going downwards). A node that has a child is called the child's parent node (or superior). All nodes have exactly one parent, except the topmost root node, which has none. A node might have many ancestor nodes, such as the parent's pare…
