Hash tables
A hash table is built on a map data structure but uses a hash function to compute an index of items into an array of values. Since data in this data structure is stored in an associative manner, you can access a desired value very fast:
The HashMap class implements this data structure and supports operations such as:
- open fun clear()
- open fun containsKey(key: K): Boolean
- open fun containsValue(value: V): Boolean
- open operator fun get(key: K): V?
- open fun put(key: K, value: V): V?
- open fun remove(key: K): V?
