I am wondering if in Python exists a data structure for which is possible induce a custom internal ordering policy. I am aware of OrderedDict and what ...
So I encountered this very weird behavior on an edge case when sorting a vector using a custom comparator. When running this code, it will not halt, ...
Consider the following code: The output is 1 where I would expect it to be 2. This seems to be due to only attr1 being compared in the operator< ...
I have a question on the code piece from C++ standard library. My question is that !(p2.lastname() < p1.lastname()) seems not to be necessary becau ...
While trying out the new Tie-Interceptor three-way comparison operator <=> I was wondering what would be an example such that would lead to ...

Consider the following struct: How do we define a strict weak ordering on x and y so that the object can be used within a std::set? Note that y can ...
I'm practicing lambdas: This is just code from GeeksForGeeks to sort in descending order, nothing special. I added some print statements (but took ...
I try to write a std::map< Vector3D, double > where colinear (parallel or anti-parallel) vectors should share the same key. As a compare funct ...
I'm trying to sort a vector of items. As mentioned in the code comments, the ordering should be: Participants with more action points (mAp) go first. ...
I have problem with strict weak ordering in the compare function in std::sort. I can't see why this would fail. I have some nested structs: In my ...
I do know that I should follow strict weak ordering for c++ comparator. And the main reason is that !(a > b) && !(b > a) should act as e ...
I have been reading on memory re-ordering lately. My question is with regarding to multi threading scenarios. Consider the example below: I have be ...
Is there any existing implementation of Python2 where ordering is transitive? That is, where it's impossible to see this behaviour without creating us ...
i Have been playing around with STL containers and the compare function/functors they supports, however i found priority_queue doesn't follow the usua ...
Field2 is not always available in my data, so sometimes I use a wildcard value of 0, which can match any value for which field1 matches. Is this val ...
I have the following problem: Consider this (simplified) structure: Now I want to have a set of all tasks and do some work with it. Therefore I hav ...
I understand that to use std::sort(), the compare function must be strict weak order, otherwise it will crash due to accessing address out of bound. ( ...
[SGI official document] Because of irreflexivity and transitivity, operator< always satisfies the definition of a partial ordering. The defini ...
