Introduction to Tree

What is a Tree?

In computer science, a tree is a hierarchical data structure that simulates a tree-like structure with a set of connected nodes. Unlike linear data structures such as arrays or linked lists, trees allow for more complex relationships and efficient organization of data. They are particularly useful for representing data that naturally forms a hierarchy, such as file systems, organizational structures, and more.

Visual Representation:

        A
       / \
      B   C
     / \   \
    D   E   F

In the above example:

  • A is the root node.

"The height of a tree is the number of edges on the longest path from the root node to the leaf node. It represents the depth of the tree from the root. In contrast, the depth of a specific node in the tree is the number of edges from the root node to that particular node."

This is confusing, what does it mean? Does it mean height is same as depth?
