what is set?
Data structures known as sets are used in computer science to hold groups of unique components. Sets' elements cannot be placed in a certain sequence since they are unordered. Sets are widely used in procedures to test for set inclusion or to check for the availability of specific members. Sets are frequently used to hold collections of related data. In addition, sets can be used to hold data from operations, such as a collection of prime integers. Hash tables, binaries trees, or other data formats are frequently used in the implementation of sets. Graphs and relations are two examples of mathematical ideas that can be modelled or described using sets. Languages for programming frequently employ sets.
