👉 Dupability, also known as redundancy or indistinguishability, is a characteristic of data structures and algorithms that refers to the inability of an object to be both identical (identicalness) and different (distinguishability). This means that if two objects are considered identical, they cannot have any common properties. Therefore, when comparing them, it is not possible to tell whether one is the same as the other without additional information. Dupability can arise in a variety of contexts, such as in databases
