What is double hashing?
Understand the Problem
The question is asking for an explanation of double hashing, which is a technique used in computer science, particularly in hash tables for resolving collisions. It involves using two hash functions to calculate the index for storing a particular key.
Answer
Double hashing is a collision resolution technique using two hash functions.
Double hashing is a collision resolution technique used in hash tables. It utilizes two different hash functions to compute two different hash values.
Answer for screen readers
Double hashing is a collision resolution technique used in hash tables. It utilizes two different hash functions to compute two different hash values.
More Information
In double hashing, the first hash function determines the initial position, while the second hash function calculates the step size for probing.
Tips
A common mistake is not choosing the second hash function appropriately, which can lead to inefficiencies.
