Hash tables are important because some PowerShell commands will understand hash tables as values for their parameters, and one of the most common PowerShell commands you would use in this scenario ...

Hash tables are used in compilers, databases, caching, associative arrays and so on. Hash tables are one of the most important data structures in computer science. The Problem. The problem that will ...

And while a hash table can find any word in a constant amount of time (usually a tiny fraction of a second), the search time for other methods can go up as the number of words in the dictionary ...

Hash tables have been around since the 1950s, and are an example of a key-value store where a hash function is used to generate the index for the data value based on the key itself.

I want to have a very large hash table, i.e. so big it won't fit into memory. What's a good way to do that? I could use a database, but since it's only going to be key => value pairs that I am ...

The talk is structured as an evolution of hash tables. The first implementation is what I learned in school so many years ago. You have an array of pointers.

And for this new hash table, the time required for worst-case queries and insertions is proportional to (log x) 2 —far faster than x. This result directly contradicted Yao’s conjecture.

Together, Krapivin (now a graduate student at the University of Cambridge), Farach-Colton (now at New York University) and Kuszmaul demonstrated in a January 2025 paper that this new hash table can ...

In the world of decentralization, distributed hash tables (DHTs) recently have had a revolutionary effect. The chaotic, ad hoc topologies of the first-generation peer-to-peer architectures have been ...
