First, they reasoned that to perform an insertion or a deletion, a hash table — or, really, any data structure — must access the computer’s memory some number of times. If they could figure out the ...

“Hash tables are among the oldest data structures we have. And they’re still one of the most efficient ways to store data.” Yet open questions remain about how they work, he said. “This paper answers ...

The design, implementation, and analysis of abstract data types, data structures and their algorithms. Topics include: data and procedural abstraction, amortized data structures, trees and search ...

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.

This will also be an introduction to the role of randomization in algorithm design. Next, we will study hashtables: a highly useful data structure that allows for efficient search and retrieval from ...
