Question: 1 / 510

What principle does hashing utilize to store and find keys quickly?

Sorting

Serializing

Random access

Indexing

Hashing does not use sorting because the order of the keys does not matter in a hash table. Serializing is a process that converts an object into a stream of bytes but it is not directly related to storing and finding keys quickly. Random access is a method of accessing specific elements in a collection but it is not specific to storing and finding keys. Indexing, however, is the process of organizing data to quickly find specific elements and is the principle utilized by hashing to store and find keys quickly.
