Are there substantive differences between the different approaches to "size issues" in category theory?

This transformation allows for faster comparison of elements during look-up, because the elements of the second takım 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

If you don't specify this, the compiler infers the type of T to be BaseClass since BaseClassComparer implements IEqualityComparer.

next, when we iterate over the query object it gets hash code for each item in the source collection and compares it with the hashes of preceding objects

There are multiple ways to tackle this and tell LINQ how the objects should be compared to each other. I will cover the use of IEqualityComparer. The interface contains two methods:

More importantly, I have stepped into the trap of thinking that objects, which I use in my code, dirilik be only partially relevant to me, while in case we do OOP every object must be considered in its entirety (things like SOLID help C# IEqualityComparer nerelerde kullanılıyor us with that.) This way, when implementing the IEqualityComparer interface I should have paid more attention to the presence of GetHashCode(..) method. This would solve my sıkıntı at once, because it is this same method that LINQ uses when asked to extract distinct objects and perform other equality related operations (see C# IEqualityComparer nedir Grup operators in this article). To verify this we add a debug message to the method and observe several calls to it:

Good news is that this same Distinct() method works for collections of our custom objects too. So if George Clooney accidentally creeps into our collection twice that's hamiş a mesele:
