|
|
* Insertion, deletion, and lookup in a hash map are all considered to be fast
|
|
* operations, amortized to O(1), or constant time.
|

*
|
|
* The word "Trie" in this API is historical. As of AMX Mod X 1.8.3, tries have
|
|
* been internally replaced with hash tables, which have O(1) insertion time
|
|
* instead of O(n).
