I need to define an unordered_map like this unordered_map<pair<int, int>, *Foo>, what is the syntax for defining and passing a hash and equal functions to this map?
I\'m looking for a hash function that I can use to give uniform unique IDs to devices that connect to our network either using a GSM modem or an ethernet connection.
I don\'t really understand why a bloom filter requires multiple hash functions (say, SHA and MD5). Why not just make a bigger SHA hash, for example, and then break it up into multiple parts and treat
As per my understanding I think: It is perfectly legal for two objects to have the same hashcode. If two objects are equal (using the equals() method) then they have the same hashcode.
Consider the following code #include <boost/unordered_set.hpp> #include <boos开发者_开发问答t/shared_ptr.hpp>
Has anyone written a generic function so that hash functions can be generated automatically for custom data types (using the deriving mechanism)? A few times, I\'ve written the following kind of boile
I have come across situations in an interview where I needed to use a hash function for integer numbers or for strings. In such situations which ones should we choose ? I\'ve been wrong in these situ
I need to compare two different files of the instance \"File\" in Java and wan开发者_如何学Ct to do this with a fast hash function.
