Hashing data structure
WebCount–min sketch. In computing, the count–min sketch ( CM sketch) is a probabilistic data structure that serves as a frequency table of events in a stream of data. It uses hash functions to map events to frequencies, but unlike a hash table uses only sub-linear space, at the expense of overcounting some events due to collisions. WebWhat is hashing ? It is a method of storing and retrieving data from hash table in O (1) time complexity. It ease the searching process as compared to other methods like binary …
