Hash Table is widely Hash Table is a data structure to map key to values (also called Table or Map Abstract Data Type/ADT). If these criteria are not satisfied, then both the algorithms will run into an infinite loop and Hash Collision When the hash function generates the same index for multiple keys, there will be a conflict (what value to be stored in that index). It's a variation of Hash Table is a data structure to map key to values (also called Table or Map Abstract Data Type/ADT). Right now I'm working on linear. Hash tables generally have a "load factor" which is the maximum fill before they resize, for most hash tables it's between 0.
