std::map è un contenitore ordinato associativo che contiene coppie chiave-valore con chiavi univoche. Le chiavi vengono ordinati utilizzando la funzione di confronto Compare. Operazioni di ricerca, di rimozione, e l'inserimento hanno complessità logaritmica. Le mappe sono generalmente implementati come alberi red-black.

Original:

std::map is a sorted associative container that contains key-value pairs with unique keys. Keys are sorted by using the comparison function Compare. Search, removal, and insertion operations have logarithmic complexity. Maps are usually implemented as alberi red-black.
