QUESTION
Giving a bit of context. I'm using c++17. I'm using pointer T* data
because this will interop with cuda code. I'm trying write a parallel version (on CPU) of a histogram creator. The sequential version:
ANSWER
Answered 2021-Jun-16 at 00:46The issue you are having has nothing to do with templates. You cannot invoke std::async()
on a member function without binding it to an instance. Wrapping the call in a lambda does the trick.
Here's an example:

I'm confused why a type that implements comparable
isn't "implicitly comparable", and also why certain syntaxes of sortWith
won't compile at all:

QUESTION
I was given this C# code to generate 10 random coordinate points. The code generates an ArrayList with the 10 coordinates, prints the objects, sorts them, and prints them again:
...ANSWER
Answered 2021-Jun-14 at 15:10For question #1, look at the documentation for Console.WriteLine()
. There are several overloads, but the one matching the way you call the function expects a string and an object. That overload knows to use the ToString()
method on the passed object. You could simplify the line even further like this, which will do the same thing:
QUESTION
If I create a set
object and add some value to this and then I add another value (smaller than before) sometimes set
sorts it and puts the new value on the begging and sometimes just ignore any orders and puts it on the very end of the set
.
Here's example with sorting:

is definitely not sorted. Keep that in mind that set
is more complicated data structure than for example List
. Here is a question which fits to yours: 'order' of unordered Python sets. You should definitely check it out.
QUESTION
I am trying to abstract the explicit creation and destruction of raw handles with the usage of classes. The actual handle is stored as a private class member (so that the user doesn't interact with the lower-level details), which is created on construction and destroyed on destruction. Is there a design pattern of some sorts that could help achieve what the code below is trying to accomplish?
Note that it is possible for there to be loads of classes interdependent to each other, therefore it would be both tedious and bad practice to pollute each class with lots of friend statements.

Answered 2021-Jun-11 at 23:06Is there a design pattern of some sorts that could help achieve what the code below is trying to accomplish?
Yes. It is called Resource Acquisition Is Initialization, or RAII for short. Your first attempt is in the right direction, but it is likely incomplete. A thing to potentially be concerned about is that typically it is an error to "destroy" a raw handle multiple times. Hence, you should establish a "class invariant" that as a post condition of every member function, no two instances of the class own the same raw handle. Your classes currently violate such invariant. Consider what happens when you make a copy of an instance. There is a rule of thumb called rule of five (previously rule of three) that will help establishing that invariant.
As for the private access and avoiding friends, a good solution is to provide a public getter:
QUESTION
I am having a hard time understanding why the Oracle CBO is behaving the way it does when a bind variable is part of a OR condition.
My environment
Oracle 12.2 over Red Hat Linux 7
HINT. I am just providing a simplification of the query where the problem is located
...ANSWER
Answered 2021-Jun-10 at 17:36From the execution plan the optimiser is, for some reason, re-evaluating the hierarchical query for every row in your table, and then using exists()
to see if that row's ID is in the result. It isn't clear why the or
is causing that. It might be something to raise with Oracle.
From experimenting I can see three ways to at least partially work around the problem - though I'm sure there are others. The first is to move the CSV expansion to a CTE and then force that to materialize with a hint:
QUESTION
(In split function) I ran it without these conditions, and it worked just as same as with them. When we get to a single node linked list, the stopping condition of merge_sort function should just return the same single node linked list back and rest can go on. I saw this in a tutorial and this was explained like " linked_list can be none when a linked_list having a single node is passed through split" Any help would be highly appreciated
...ANSWER
Answered 2021-Jun-12 at 06:34You are right, you don't need those conditions in the split(linkedlist)
function because you are making the check for edge cases in the merge_sort(linkedlist)
function.
I suppose the tutorial that you referred included it two times to make split(linkedlist)
work as a standalone function i.e. it will work on any LinkedList.
QUESTION
I've been developing an site and everything seemed to be going fine. I was sending my dates by converting them to ISO format as it's the only thing my C# WebAPI would accept (that I can work out). However I found that now we're in June and try for example to send 10/06/2021. The date sent would now have a day subtracted from them.
I've tried all sorts of different things. But they either turn out as invalid data or just in American format?

Install sorts
You can use sorts like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
