The rank of a node value in a tree is the number of the nodes whose values are . The nodes can be of any data type as long as it comes with an ordering relation . For example, the rank of in the following tree is : So, we have a value and the root of a tree, and the goal is to find the ‘s rank in it.

WebReading time: 15 minutes Coding time: 5 minutes. Depth-first search (DFS) algorithm is an algorithm for traversing or searching tree or graph data structures. One starts at the root (selecting some arbitrary node as the root in the case of a graph) and explores as far as possible along each branch before backtracking. WebPath − Path refers to the sequence of nodes along the edges of a tree. Root − The node at the top of the tree is called root. There is only one root per tree and one path from the root node to any node. Parent − Any node except the root node has one edge upward to a node called parent.
