Hash tables are one of the oldest and simplest data structures for storing elements and supporting deletions and queries. Invented in 1953, they underly most computational systems. Yet despite their ...

The concept of soft delete is, if we have elements on index 3,5,7,10 and when deleting a key it say its hash values lands on index 5, i would not "hard delete" it, because then we will make 3 and 7,10 ...

Abstract: Chord DHT (Distributed Hash Table) is a robust solution to a basic problem encountered in peer-to-peer (P2P) applications: efficiently locating the node that stores specific data items. In ...

After looking at the recent GoLang update for curiosity, I noticed one standout item. GoLang now uses Swiss Tables for mapping. I'd not heard of this algorithm, so it took a bit of searching to come ...

A young computer scientist and two colleagues show that searches within data structures called hash tables can be much faster than previously deemed possible. Sometime in the fall of 2021, Andrew ...

Computing practitioners encounter hash functions almost every day, although they may not necessarily be the center of attention. When you install software packages or updates, the authenticity of a ...
