QUESTION
For example, given a List of Integer List list = Arrays.asList(5,4,5,2,2), how can I get a maxHeap from this List in O(n) time complexity?
The naive method:
...ANSWER
Answered 2021-Aug-28 at 15:09According to the java doc of PriorityQueue(PriorityQueue)
Creates a PriorityQueue containing the elements in the specified priority queue. This priority queue will be ordered according to the same ordering as the given priority queue.
So we can extend PriorityQueue as CustomComparatorPriorityQueue to hold the desired comparator and the Collection we need to heapify. Then call new PriorityQueue(PriorityQueue) with an instance of CustomComparatorPriorityQueue.
Below is tested to work in Java 15.
QUESTION
I am getting this error when I try to sign up a user. After this error, I'm still able to sign in with the user it would've created, but it always shows me this upon registration. Please let me know if there's other information you need. Been stumped on this for a few days.
Here is the callback for the error:

Answered 2022-Jan-03 at 12:08This seems to a be a known issue with Rails 7 and Devise now. To fix it in the meantime simply add the following line to your devise.rb.
config.navigational_formats = ['*/*', :html, :turbo_stream]
QUESTION
I'm upgrading from JDK 8 to JDK 17 and I'm trying to compile with mvn clean install -X -DskipTests and there's no information about the error.
Btw, I'm updating the dependencies and after that I compile to see if has errors. I need to update some dependencies such as Spring, Hibernate etc. I already updated Lombok.
I added the -X or -e option but I got the same result.
What can I do to get more information about the error? The log shows that it was loading hibernate-jpa-2.1-api before failed... so that means the problem is in this dependency?
...ANSWER
Answered 2021-Oct-19 at 20:28This failure is likely due to an issue between java 17 and older lombok versions. Building with java 17.0.1, lombok 1.18.20 and maven 3.8.1 caused a vague "Compilation failure" for me as well. I upgraded to maven 3.8.3 which also failed but provided this detail on the failure:
java.lang.NullPointerException: Cannot read field "bindingsWhenTrue" because "currentBindings" is null
Searching for this failure message I found this issue on stackoverflow leading me to a bug in lombok. I upgraded to lombok 1.18.22 and that fixed the compilation failure for a successful build.
QUESTION
I've built this new ggplot2 geom layer I'm calling geom_triangles (see https://github.com/ctesta01/ggtriangles/) that plots isosceles triangles given aesthetics including x, y, z where z is the height of the triangle and
the base of the isosceles triangle has midpoint (x,y) on the graph.
What I want is for the geom_triangles() layer to automatically provide legend components for the height and width of the triangles, but I am not sure how to do that.
I understand based on this reference that I may need to adjust the draw_key argument in the ggproto StatTriangles object, but I'm not sure how I would do that and can't seem to find examples online of how to do it. I've been looking at the source code in ggplot2 for the draw_key functions, but I'm not sure how I would introduce multiple legend components (one for each of height and width) in a single draw_key argument in the StatTriangles ggproto.
ANSWER
Answered 2022-Jan-30 at 18:08I think you might be slightly overcomplicating things. Ideally, you'd just want a single key drawing method for the whole layer. However, because you're using a Stat to do the majority of calculations, this becomes hairy to implement. In my answer, I'm avoiding this.
Let's say I'd want to use a geom-only implementation of such a layer. I can make the following (simplified) class/constructor pair. Below, I haven't bothered width_scale or height_scale parameters, just for simplicity.

I am trying to try a sample project in Flutter integration email and google based login, and planning to use firebase initialisation for doing it while I have followed all the steps as mentioned in tutorials I am getting this error as soon as firebase is attempted to be initialised.

For your firebase_core version is seems to be sufficient to pass the FirebaseOptions once you initialize firebase in your flutter code (and you don't need any script tags in your index.html):

...ANSWER
Answered 2021-Dec-22 at 09:27What is considered best practice for aborting on errors in C?
What is a good practice, that would be considered idiomatic to C?
Really, nothing. There is no best-practice. Best is to tailor a specific solution to the specific case you are handling. For sure - concentrate on writing readable code.
Let's mention some documents. MISRA 2008 has the following. The rule is strict - single exit point. So you have to assign variables and jump to a single return statement
Rule 6–6–5 (Required) A function shall have a single point of exit at the end of the function.
Error handling is the only place where using goto is actually encouraged. Linux Kernel Coding style presents and encourages using goto to "keep all exit points close". The style is not enforced - not all kernel functions use this. See Linux kernel coding style # Centralized exiting of functions.
The kernel recommendation of goto was adopted by SEI-C: MEM12-C. Consider using a goto chain when leaving a function on error when using and releasing resources.
Does the do { } while(0); pattern qualify?
Sure, why not. If you do not allocate any more resources inside the do { .. here .. }while(0) block, you might as well write a separate function and then call return from it.
There are also expansions on the idea. Even implementations of exceptions in C using longjmp. I know of ThrowTheSwitch/CException.
Overall, error handling in C is not easy. Handling errors from multiple libraries becomes extremely hard and is an art of its own. See MBed OS error-handling, mbed_error.h, even a site that explains MBed OS error codes.
Strongly prefer single return point from your functions - as you found out, using your CHECK(errorcode); will leak resources. Multiple return places are confusing. Consider using gotos:
QUESTION
I want to build an Android app which will be an interface to convert C++ into assembly code for ARM Cortex M3 architecture.
I'm not an android java developer, and I do mainly arduino projects with C/C++. So I need your help to point me in good directions about how to build an android app with java in Android Studio or similar, which will be able to convert from C++ source code to ASM code M3 Cortex.
I did some research and found that I need to use ARM NONE EABI GCC compiler to generate ASM code from C++, simple like these command line instructions:
...ANSWER
Answered 2021-Dec-16 at 16:58A solution would be if in Termux app you will do next things: (more details here)
pkg install prootpkg install proot-distroproot-distro install debianproot-distro login debian
After that you should be logged in a Debian environment, and you can install almost any Arm packages available on debian repositories.
For example you should be able to install this Cortex compiler:
QUESTION
I have read many articles about static/dynamic library/framework. So my understanding is (let me know if it's inaccurate):
...ANSWER
Answered 2021-Dec-12 at 16:13Why there's no "Dynamic Library" option?
Because Dynamic Library is not permitted for iOS apps at beginning.
Given that we can already link framework statically, why do we still need a "Static Library"? (isn't StaticFramework = StaticLibrary + Bundle? )
Because old Xcode only support Static Library.
Static Framework was added later, and they keep the Static Library.
QUESTION
I've successfully written my application using Axios to fetch content. As of now, it's set up to fetch content when certain events happen (like the submit button has been clicked.) However, I'm experimenting with Redux's RTK-Query solution. This package generates hooks and in their examples, they provide simple component-level examples that call the hooks on mount.
How can I leverage these rtk-hooks (and hooks in general) so I can tie them to behaviors like onClick, onSubmit, and conditional events? I'm aware this conflicts with the rules-of-hooks guidelines, but I can't imagine RTK-Query would be so limited as to only allow component-level onMount API calls.
some related articles I'm reading while I try to figure this out / wait for a helpful example:
- https://blog.logrocket.com/react-hooks-frustrations/
- https://redux-toolkit.js.org/rtk-query/usage/usage-without-react-hooks
The second article seems somewhat relevant but I feel like its beating too far off the path and is making question if it's even worth having rtk-query installed. I might as well just use axios since it can be used anywhere in my components and logic. Can someone educate me on how to approach this problem? I'm new to rtk-query, it seems really cool but it also seems really restrictive in its implementation approaches.
