Graph data structures are fundamental in computer science and have a wide range of applications, from social networks to transportation systems. When representing graphs in computer memory, two common approaches are the adjacency list and the adjacency matrix. In this blog post, we'll explore these two representations, compare their characteristics, and discuss their practical applications. Explanation of Graph Data Structures Graphs consist of nodes (vertices) connected by edges. They can be categorized into directed graphs (where edges have a direction) and undirected graphs (where edges have no direction). Graphs can also be weighted, meaning edges have associated values or weights. Comparison of Adjacency List and Adjacency Matrix Adjacency List An adjacency list represents a graph as an array of linked lists or arrays. Each element in the array corresponds to a vertex, and its linked list or array contains the vertices adjacent to that vertex. Adjacency Matrix An adjacency ...

In today's digital age, recommendation engines play a pivotal role in enhancing user experience across various platforms, from e-commerce websites to streaming services.
