Add/Remove & Search in Hash Table (Implementation)
Explore the implementation of key hash table operations in C#, including adding, searching, and removing entries. Understand how to handle collisions, update values, and resize the table to maintain efficiency. This lesson helps you build practical skills in managing hash table data structures used in coding interviews and real-world programming.
We'll cover the following...
In the previous lesson, you built a HashTable class and designed a hash function. Using that code, implement the main functionalities of a hash table.
Insertion in hash table
Insertion in hash tables is a simple task, and it usually takes a constant amount of time. When the hash function returns the index for your input key, check if there is a hash entry already present at that index (if it does, then a collision has occurred). If not, simply create a new hash entry for the key/value. However, if the index is not null, traverse through the bucket to check if an object with your key ...
