WebHash tables are a data structure that can be implemented as a linear or non-linear data structure. Often, they are implemented as a linear data structure. Hash tables are used to map keys to values. If you had a list of names, for example, a hash table might be used to identify a person’s phone number using their name. Usually, hash tables ... WebHash tables are used to quickly store and retrieve data (or records). Records are stored in buckets using hash keys Hash keys are calculated by applying a hashing algorithm to a chosen value (the key value) contained within the record. This chosen value must be a common value to all the records. The Hash table data structure stores elements in key-value pairs where Key - unique integer that is used for indexing the values Value - data that are associated with keys.
