hashtaulukoiden
Hashtaulukot, also known as hash tables or hash maps, are data structures that implement an associative array abstract data type. They provide efficient key-value storage and retrieval. The core idea behind a hash table is to use a hash function to compute an index, or "hash code," into an array of buckets or slots. Ideally, the hash function distributes keys uniformly across these buckets.
When an element is inserted, its key is passed through the hash function, which generates an index.
However, hash collisions can occur when two different keys hash to the same index. Various collision resolution
