Question

Accepted Answer

Graph

Use a graph data structure to represent people as nodes and friend relations as edges
Each person can be represented as a node with their unique identifier
Friend relations can be represented as directed edges between nodes
This allows for efficient traversal and retrieval of friend connections

Accepted Answer

The ideal data structure to represent people and friend relations in Facebook would be a graph data structure.

In a graph, each person would be represented as a node, and each friend connection between people would be represented as an edge between the nodes. This would allow for efficient traversal and analysis of the relationships between individuals.

Additionally, the graph could be augmented with additional properties such as user data, post history, and other metadata to allow for more sophisticated analysis and recommendation systems.

Overall, the graph data structure would provide a flexible and scalable way to represent the complex network of relationships between people in Facebook.
