Tree Node
Domain: Data Structures
🎯 Motivation
A tree node stores data plus pointers to its children (and sometimes its parent). It is the building block of all tree structures.
📋 Concrete Example
A binary tree node: {value: 42, left: child1, right: child2, parent: rootnode}. The left and right pointers link to subtrees.
🔗 Analogy
A manager in a company org chart. The manager (node) has their own title (data) and reports to a boss (parent) while managing several team members (children).
