10 Questions
What is the method of hashing that uses a selection of digits as the key?
Extraction
What is the assumption made when extracting 3 digits as the key?
The part of the key is least likely to repeat
What is the purpose of using the modulus operator in hash functions?
To ensure the indices are in the desired range
What happens when the majority of keys end in a 0 in the hash table?
Collisions increase
What is the advantage of the extraction method of hashing?
It is extremely simple and efficient
What is the disadvantage of the extraction method of hashing?
Part of the key is used, resulting in less variation
What is the purpose of using the hash function h(K) = K % T?
To ensure the indices are in the desired range
What is the range of values returned by the modulus operator in hash functions?
[0, T - 1]
What is the requirement for the indices generated by the hash function?
They must be in the range [0, T - 1]
What is the result of using the hash function h(K) = K % 10 when the majority of keys end in a 0?
Collisions occur everywhere
Test your knowledge of searching algorithms, including average and worst case scenarios, in different data structures such as arrays, linked lists, skip lists, BST, and B-Tree. Learn about the efficiency of searching, inserting, and deleting in each data structure.
