Cool! The mysterious System#identityHashCode, why is it needed, I have come upon a situation where I myself have to use it. Because of the way HashMap overrides #hashCode

Після десятиліть проведення змагань із програмування — #HashCode, #KickStart, #CodeJam — #Google скасував їх.

Причина скасування — Google переглядає пріоритети. Тому всіх менеджерів, які займалися проведенням змагань, звільнено.🤷‍♂️

@ro By "I first get coordinate-pair from existing object reference", I meant I try to look up from the hypothetical thingy, the coordinate-pair for the object reference. The object doesn't store its own coordinates right now, that's one way I could solve it but question was which type of solution you prefer

Java can do it because Object has #hashCode, so all objects are hashable. I got potato'd in Python last week cause I got a unhashable type, but I didn't consider that..
