Hashing Questions
The main difference between a hash table and a graph is their underlying data structure and the way they organize and store data.
A hash table is a data structure that uses a hash function to map keys to an array index, allowing for efficient retrieval and storage of data. It is typically used for fast lookup and insertion of key-value pairs. Hash tables provide constant-time average case complexity for search, insert, and delete operations.
On the other hand, a graph is a data structure that consists of a set of vertices (nodes) connected by edges. It is used to represent relationships or connections between different entities. Graphs can be directed or undirected, and they can have weighted or unweighted edges. Graphs are commonly used for modeling networks, social relationships, and various other real-world scenarios. Graphs typically require more complex algorithms for traversal and manipulation compared to hash tables.
In summary, the main difference between a hash table and a graph lies in their data structure and the purpose they serve. Hash tables are primarily used for efficient key-value storage and retrieval, while graphs are used to represent relationships and connections between entities.
