Gethashcode why 397

I'm quite new to Perl and I'm trying to build a hash recursively and getting nowhere. I tried searching for tutorials to dynamically build hashes, Is there a pure lua implementation of the md5 hashing algorithm? One that doesn't rely on any c or external libraries? There's javascript implementations that What is happening below seems a little strange to me. If I run the below code then the output is 2 which means that the set contains 2 elements.

If you or someone else will figure out the mystery behind , please drop me note.

GetHashCode is assumed to be cheap compared to Equals. Thank you for taking the time to write this article in such clear terms. Thank you also to the folks who took time out to write the follow-up comments. When you use it to override the equality members of a class, the code-gen it produces for GetHashCode looks like:. Probably because is a prime of sufficient size to cause the result variable to overflow and mix the bits of the hash somewhat, providing a better distribution of hash codes.

There's nothing particularly special about that distinguishes it from other primes of the same magnitude. Equality by reference is the correct default in that case. Equality by value - i. In Akka. NET all message classes are supposed to be immutable, which means a reference to a message is useless as soon as someone modifies it because it creates a copy.

Therefore the Akka. NET development team has had a lot of practice implementing equality by value on many of the built-in message classes. The important distinction between this Equals method and the built-in object.

Equals object o one that comes with every.
