This transformation allows for faster comparison of elements during look-up, because the elements of the second kaş are easier to compare and because there are fewer of them. Still, due to this same reason any hash function might eventually produce equal codes for non equal objects

Alternatively, you kişi write an empty comparer class that implements IEqualityComparer, and then pick the corresponding quick-fix from the Alt+Enter menu:
