GATE DS&AI 2024 | Question: 11
Consider performing uniform hashing on an open address hash table with load factor $\alpha=\frac{n}{m}<1$, where $n$ elements are stored in the table with $m$ slots. The expected number of probes in an unsuccessful search is at most $\frac{1}{1-\alpha}$. Inserting ... $\frac{1}{1-\alpha}$ $1+\frac{\alpha}{2}$ $\frac{1}{1+\alpha}$

Kotidis I., First Exercise Pack 2021-2022.
Consider an extendible hash index, each bucket of which holds N entries. What is the probability that an overflowed bucket needs to be dealt with recursively? “Dealt with recursively” means that all of this bucket’s records are moved to one of the two new buckets that will be created.

GATE CSE 2023 | Question: 10
An algorithm has to store several keys generated by an adversary in a hash table. The adversary is malicious who tries to maximize the number of collisions. Let $k$ be the number of keys, $m$ be the number of slots in the hash ... a carefully chosen constant. Universal hashing method. If $k$ is a prime number, use Division method. Otherwise, use Multiplication method.

DRDO CSE 2022 Paper 2 | Question: 22
A hash table contains $10$ buckets and uses linear probing to resolve collisions. The key values are intergers and the hash function used is $\text{Key}\%10.$ If we insert values $43,165,62,123,152$ sequentially in the table, in what bucket will the key $152$ be inserted?
