Onto function mapping
Web5 de dez. de 2014 · Given a collection and a set of relations between them, I'd like to check if there exists a one-to-one & onto subset in the relations. (Ideally I'd also like to GET those subsets) For example: Stack Overflow. About; ... mapping = collections.defaultdict(list) for key, value in relations: mapping[key].append(value) A function is surjective or onto if each element of the codomain is mapped to by at least one element of the domain. In other words, each element of the codomain has non-empty preimage. Equivalently, a function is surjective if its image is equal to its codomain. A surjective function is a surjection. The formal definition is the following.
