An “n number look up” is a technique for finding information stored in a data structure, where “n” represents an input value that determines the location of the desired data. For instance, in a phone book, the “n number” would be a name or phone number, and the corresponding entry would be retrieved.
N number look ups are essential for efficiently accessing data in a wide range of applications. They enable quick retrieval of information, enhance data organization and management, and have historically evolved alongside technology developments, such as the introduction of binary search and hash tables.
