misura del numero di elementi di un insieme
Cardinality is a mathematical property that describes how many individual objects are in a set, whether that number is finite or infinite. It's determined by checking if the objects in two sets can be paired up perfectly—if every object in one set matches with exactly one object in another set with nothing left over, then the sets have the same cardinality.
