why can't return assignment statement : <p>In IDLE,
I write a function and intend to return a value. but it can't return</p>
<pre><code>>>> def grade(value):
if value > 100:
return (value=100)
if value <0:
return (value=0)
SyntaxError: invalid syntax
</code></pre>
<p>why can't return? but when I change to</p>
<pre><code>value = 100
return value
</code></pre>
<p>It can work</p>

how to select 1 date field with 3 tags : Good day, i'm making query that select 1 datefield 3 times.
`select t1.datefield date_1, t1.datefield date_3, t1.datefield date_3 from table t1 where t1.datefield BETWEEN TO_DATE('01/07/2016', 'dd/mm/yyyy') AND TO_DATE('31/07/2016', 'dd/mm/yyyy')`
i need date_1 between July 01 and July 31, date_2 between August 01 and August 31, date_3 between Septembre 01 and September 30
How can i do that?

Nested constexpr-if statement in discarded branch is still evaluated? : <p>It appears to me that a constexpr-if statement that is inside the discarded branch of another constexpr-if statement is evaluated in MSVC (version 15.7.3).</p>
<p>Consider the following code:</p>
<pre><code>#include <tuple>
#include <type_traits>
template <size_t I>
int test() {
if constexpr(I != 0) {
return 0;
}
else { // This branch is discarded, but it seems that the constexpr-if below is still evaulated?
if constexpr(std::is_same_v<int, std::tuple_element_t<I, std::tuple<int>>>) { // some constexpr check that is valid only when I == 0
return 1;
}
else {
return 2;
}
}
}
int main() {
test<1>();
return 0;
}
</code></pre>
<p>The code above fails to compile in MSVC, because <code>std::tuple_element_t</code> will fail a static assertion when <code>I</code> exceeds the bounds of the tuple. This suggests that somehow the code in the discarded branch was evaluated as well, even though it is dependent on the template parameter <code>I</code>.</p>
<p>According to <a href="http://en.cppreference.com/w/cpp/language/if#Constexpr_If" rel="noreferrer">cppreference</a>, constexpr-if requires that "the discarded statement can't be ill-formed for every possible specialization", but I'm having a hard time deciding if this is the case here.</p>
<p>It also seems that GCC and Clang accepts this code without issue (tested on Compiler Explorer).</p>
<p>Is the compilation error acceptable by the C++ standard, or is MSVC non-compliant here?</p>
<p>(Also, if what I'm expecting the code to do isn't guaranteed by the standard, is there another way to accomplish nested constexpr-if statements?)</p>

powershell generate word list from two csv files and export to csv : I'm trying to use powershell to import two csv files, one csv is called accts and one is called names. The accts file has 8 numbers and the names files has 4 names. I need to output a combination where the end goal is to output a list of 32 words with the prefix of STX. I'll take this list of 32 and create 32 AD objects. Ideally I need to also run a check to see if the word/AD object already exists.
accts:
12345
23456
34567
45678
56789
67890
78901
89012
names:
john
dave
joe
mike
output should be:
stx-12345-john
stx-23456-john
stx-34567-john
stx-45678-john
stx-56789-john
stx-67890-john
stx-78901-john
stx-89012-john
stx-12345-dave
stx-23456-dave
stx-34567-dave
stx-45678-dave
stx-56789-dave
stx-67890-dave
stx-78901-dave
stx-89012-dave
etc
I've thought about trying to use arrays, but perhaps that would be to complex. Any advice? Sorry I don't do a lot of PS on a consistent basis.

How to use axios instead of ajax in datatable? : <p>I want to use axios to fetch data and load them to datatable. It is possible if I load all the data and render to datatable. But, what I want is load page number specific data. I don't want to load all the data at once it makes slow data loading. In short, I want to implement server side loading with axios in datatable. I have been stuck since long. Is there any way? Thanks.</p>

How to compare randomly generated number with user entered number at run time in C? : <p>I am making Bubble game in c where randomly some numbers are generating on the console window and user need to enter that numbers appearing on the screen or console window and I need to compare that user input and random generated number and make that number invisible from the screen.</p>
<p>I have used rand() function in c and for user input I have used getch() function and i have tried every type conversion but not getting the solution yet.</p>
<pre><code>void main() {
char temp1 = 0;
char temp = 0;
temp1 = rand()%10;
temp = getch();
if(temp == temp1)
printf("ok");
}
</code></pre>
<p>I want to compare randomly generated value and user input at run time and input given by the user by seeing on console's number is equal i want to exit.</p>

In python, is math.acos() faster than numpy.arccos() for scalars? : <p>I'm doing some scientific computing in Python with a lot of geometric calculations, and I ran across a significant difference between using <code>numpy</code> versus the standard <code>math</code> library.</p>
<pre><code>>>> x = timeit.Timer('v = np.arccos(a)', 'import numpy as np; a = 0.6')
>>> x.timeit(100000)
0.15387153439223766
>>> y = timeit.Timer('v = math.acos(a)', 'import math; a = 0.6')
>>> y.timeit(100000)
0.012333301827311516
</code></pre>
<p>That's more than a 10x speedup! I'm using numpy for almost all standard math functions, and I just assumed it was optimized and at least as fast as <code>math</code>. For long enough vectors, numpy.arccos() will eventually win vs. looping with math.acos(), but since I only use the scalar case, is there any downside to using math.acos(), math.asin(), math.atan() across the board, instead of the numpy versions?</p>

Counting the no of elements in a data structure, printing the count for each position and decrement the iteration using recursion : Various signal towers are present in a city.Towers are aligned in a straight horizontal line(from left to right) and each tower transmits a signal in the right to left direction.Tower A shall block the signal of Tower B if Tower A is present to the left of Tower B and Tower A is taller than Tower B. So,the range of a signal of a given tower can be defined as :
{(the number of contiguous towers just to the left of the given tower whose height is less than or equal to the height of the given tower) + 1}.
#include <iostream>
#include <vector>
using namespace std;
vector<int> res;
void recursion(int a[],int x)
{
if (x >= 0)
{// Taking the last element of the array as the max element
int max = a[x], count = 0;
for (int i = x; i >= 0; i--)
{//Comparing the max with all the elements in the array
if (max >= a[i])
{
count++;
}
else
{
break;
}
}
//Pushing the count of the current element in the vector.
res.push_back(count);
x = x - 1;
recursion(a, x);
}
}
int main() {
int TestCase, n;
cin >> TestCase;
for (int l = 0; l < TestCase; l++)
{
cin >> n;
int * arr = new int[n];
//Getting the elements
for (int j = 0; j < n; j++)
{
cin >> arr[j];
}
recursion(arr, n-1);
//Iterating through the vector in reverse manner and printing
//the result.
for (auto it = res.rbegin(); it != res.rend(); ++it)
{
cout << *it << " ";
}
delete[] arr;
}
return 0;
}
First line contains an integer T specifying the number of test cases.
Second line contains an integer n specifying the number of towers.
Third line contains n space separated integers(H[i]) denoting the height
of each tower.
Print the range of each tower (separated by a space).
Sample Input :
1
7
100 80 60 70 60 75 85
Sample Output :
1 1 1 2 1 4 6

What is a good alternative for static stored properties of generic types in swift? : <p>Since static stored properties are not (yet) supported for generic types in swift, I wonder what is a good alternative.</p>
<p>My specific use-case is that I want to build an ORM in swift. I have an <code>Entity</code> protocol which has an associatedtype for the primary key, since some entities will have an integer as their <code>id</code> and some will have a string etc. So that makes the <code>Entity</code> protocol generic.</p>
<p>Now I also have an <code>EntityCollection<T: Entity></code> type, which manages collections of entities and as you can see it is also generic. The goal of <code>EntityCollection</code> is that it lets you use collections of entities as if they were normal arrays without having to be aware that there's a database behind it. <code>EntityCollection</code> will take care of querying and caching and being as optimized as possible.</p>
<p>I wanted to use static properties on the <code>EntityCollection</code> to store all the entities that have already been fetched from the database. So that if two separate instances of <code>EntityCollection</code> want to fetch the same entity from the database, the database will be queried only once.</p>
<p>Do you guys have any idea how else I could achieve that?</p>

<p>Now, I'm not sure how to use this information. It seems to appear randomly in the app. How can I debug the app to avoid potential out-of-memory crashes? I checked in task manager that at the moment when this information appears the app uses about 55K memory which in case of this app is quite low (when it computes some data it can be much higher memory consumption).</p>
<p>So I'm wondering if this information is accurate and there is a risk of crashing. If so, what should I do with it?</p>

React Native Make View "Hug" the Top of the Keyboard : <p>Let's say I have a view that is positioned absolute at the bottom of the screen. This view contains a text input. When the text input is focused, I want the bottom of the view to touch the top of the keyboard. </p>
<p>I've been messing around with KeyboardAvoidingView, but the keyboard keeps going over my view. Is it not possible to make this work with position absolute?</p>
<p>What other method can I try? Thanks!</p>

Angular2 detect change in service : <p>I have one component in Angular2 which is changing a "lang" class variable in my service translate.service.ts. In another component I am fetching a dict with the translation on init. If the first component changes the services language later, I want to refetch the dict in the second component automatically. How do I do that?</p>
<p>First component:</p>
<pre><code> setLang(lang) {
this._translateService.setLang(lang);
}
</code></pre>
<p>Service:</p>
<pre><code>dict = { "en": {}};
lang = "en";
setLang(lang) {
this.lang = lang;
}
getLang() {
return this.dict;
}
</code></pre>
<p>Second component:</p>
<pre><code>ngOnInit() {
this.dict = this._translateService.getDict();
}

Multi Threading in API in C# : <p>I'm trying to create an Web Service that runs an asynchronous function with .Net Core Framework.</p>
<p>This function must be executed in its own thread and return a new value that will be sent to the proper caller.
The service must be listening for other calls while my async function is running, and start a new thread for each call.
Once the thread is finished, I want the response to be sent to the original caller.
I have tried this way :</p>
<p>In my controller I have :</p>
<pre><code>[Route("api/orchestration")]
public class OrchController : Controller
{
[HttpGet("{value}")]
public void RunOrchestration(int value)
{
Program.GetResultAsync(value); // Notice that no value is returned but it respects the asynchronicity and the multithreading as asked
}
}
</code></pre>
<p>In my main class I have :</p>
<pre><code>public async static Task<string> GetResultAsync(int i)
{
return await OrchestrationAsync(i);
}
public static Task<string> OrchestrationAsync(int i)
{
return Task.Run<string>(() => { return r = Orchestration(i); });
}
public static string Orchestration(Object i)
{
// This function is an orchestrator of microservices that talk asynchronously through a MOM
// Just consider that it returns the value I want in a string
return result;
}
</code></pre>
<p>As you can see I want my function GetResultAsync to return a string with the value that will be sent to the caller.
Yet I can't have something like this (see code below) because GetResultAsync returns a Task and not a string :</p>
<pre><code>public string RunOrchestration(int value)
{
return r = Program.GetResultAsync(value);
}
</code></pre>
<p>And if I put an await in RunOrchestration, it will wait for the response and will behave as a synchronous function.</p>
<p>Anyone has an idea on how to get my response and give it back to the proper caller ?</p>
<p>Thank's in advance ! :)</p>

R: Writing list with elements of different classed into a text file : How to write a list of different class variables into a text file consequently using R base functions?
`write` and `cat` can't handle data.frames and `write.table` is specific to tables only. None of them handles lists properly.
Sample list:
> test
[[1]]
[1] "a" "b" "c"
[[2]]
[1] "d" "e" "f"
[[3]]
[1] 1 2 3
[[4]]
X.g. X.h. X.i.
1 g h i
[[5]]
[[5]][[1]]
[1] "k"
[[5]][[2]]
[1] "l"
[[5]][[3]]
[1] "m" "n"
[[6]]
[1] "2015-03-23 11:15:00 CET"
It consists of character, numeric, POSIXlt time variable and another list.
Desired result - a text file like that:
a b c
d e f
1 2 3
X.g. X.h. X.i.
1 g h i
k
l
m n

React Navigation: How to update navigation title for parent, when value comes from redux and gets updated in child? : <p>I'm using <a href="https://github.com/react-community/react-navigation" rel="noreferrer">react-navigation</a> and have a StackNavigator with a <strong>ParentScreen</strong> and a <strong>ChildScreen</strong>.</p>
<p>Both screens have the same navigation bar with a dynamic value from redux. Implemented like described in <a href="https://github.com/react-community/react-navigation/issues/313" rel="noreferrer">Issue #313</a></p>
<p>This works as expected. When I'm in DetailScreen and I update the value for the count variable, it also updates the value in the navigation bar.</p>
<p>Problem is, if I go back to the parent scene, there is still the old value in the navigation bar. It doesn't update to the current value in redux store.</p>

tsconfig.json for project with `src` and `tests` : <p>I've got a (desired) structure like this:</p>

- src
- app.ts
- tests
- appTest.ts
- appTest.js

<p>If there was no <code>tests</code> folder, a tsconfig.json like this would work fine:</p>
<pre><code>{
"compilerOptions": {
"outDir":"dist"
},
"include" :[
"src/**/*.ts"
]
}
</code></pre>
<p>However, if I add <code>tests/**/*.ts</code> to the <code>include</code> element, it also compiles my test files into <code>dist</code> and changes its folder structure (understandably, but undesirably).</p>
<p>Can I tell TypeScript compiler to include test files in the project to support things like refactoring but omit them from output to <code>dist</code>? Specifically, I'd like the <code>.js</code> to be compiled in the <code>tests</code> directory as suggested in the structure above.</p>

Javascript Date Library that uses online API? Rather than client machine? : I'm writing a node.js package that I want to distribute. I want a function to run at a certain time... but I don't want to use any of the popular JS libraries because they use the client's machine to determine date - rather I don't want this to be alterable.
Basically the script should break after a certain date and should not be able to be reverse by changing your PC's time. Is this possible?
P.S. I have no desire to create another server to serve this date. But that's the outcome I want to achieve.

Python3 - TypeError: module.__init__() takes at most 2 arguments (3 given) : <p>Please don't mark as duplicate, other similar questions did not solve my issue.</p>
<p>This is my setup</p>
<pre><code>/main.py

<p>Main.py:</p>

self.view_id = view_id
def build_uri():

</code></pre>
<p>Running:</p>
<pre><code>$ python3 main.py

<p>The only error message I receive is: </p>

<p>Even if I try for the python3 console, I received the same error message:</p>
<pre><code>$python3

<p>I am new to Python, but not new to programming. I'm assuming that my error messages have to do with the import statements, but based on the message I can't really figure out what it means.</p>

Codepipeline: Insufficient permissions Unable to access the artifact with Amazon S3 object key : <p>Hello I created a codepipeline project with the following configuration:</p>
<ul>
<li>Source Code in S3 pulled from Bitbucket.</li>
<li>Build with CodeBuild, generating an docker image and storing it into a Amazon ECS repository.</li>
<li>Deployment provider Amazon ECS.</li>
</ul>
<p>All the process works ok until when it tries to deploy, for some reason I am getting the following error during deployment:</p>
<blockquote>
<p>Insufficient permissions Unable to access the artifact with Amazon S3
object key 'FailedScanSubscriber/MyAppBuild/Wmu5kFy' located in the
Amazon S3 artifact bucket 'codepipeline-us-west-2-913731893217'. The
provided role does not have sufficient permissions.</p>
</blockquote>
<p>During the building phase, it is even able to create a new docker image in the ECS repository. </p>
<p>I tried everything, changed IAM roles and policies, add full access to S3, I have even setted the S3 bucket as public, nothing worked. I am without options, if someone could help me that would be wonderful, I have poor experience with AWS, so any help is appreciated. </p>

search regex for Notepad++ : I am looking to create a regex for searching Notepad++
I have a notepad page with thousands of random codes such as:
415615610230
151156125611
161651651516
511111115165
I need to search the entire notepad for multiple codes with once search
I know the regex would look like (415615610230|151156125611|161651651516)
but what I need to do is build a regex like above by pasting in all my search criteria.
If I have say 100,000 numbers I might need to search the 100,000 numbers for 20 codes/numbers.
lets just say I want to search for
5155584865
5155584866
5155584867
5155584868
5155584869
5155584870
5155584871
5155584872
5155584873
5155584874
5155584875
5155584876
5155584877
5155584878
5155584879
5155584880
5155584881
5155584882
5155584883
5155584884
The regex should look like:
(5155584865|5155584866|5155584867|5155584868|5155584869|5155584870|5155584871|5155584872|5155584873|5155584874|5155584875|5155584876|5155584877|5155584878|5155584879|5155584880|5155584881|5155584882|5155584883|5155584884)
Is there a way to build the regex above by just pasting in
5155584865
5155584866
5155584867
5155584868
5155584869
5155584870
5155584871
5155584872
5155584873
5155584874
5155584875
5155584876
5155584877
5155584878
5155584879
5155584880
5155584881
5155584882
5155584883
5155584884
Or can anyone recommend an easier way to search the entire notepad document?

Overload method for unique_ptr and shared_ptr is ambiguous with polymorphism : <p>Coding stuff after taking the hint from my <a href="https://stackoverflow.com/questions/53444116/ownership-with-a-physical-representation">previous question</a>'s answer, I ran into an issue with overloading Scene::addObject.</p>
<p>To reiterate the relevant bits and make this self contained, with the least details possible:</p>
<ul>
<li>I have a hierarchy of objects inheriting from <code>Interface</code> of which there are <code>Foo</code>s and <code>Bar</code>s;</li>
<li>I have a <code>Scene</code> which owns these objects;</li>
<li><code>Foo</code>s are to be <code>unique_ptr</code>s and <code>Bar</code>s are to be <code>shared_ptr</code>s in my main (for reasons explained in the previous question);</li>
<li>the <code>main</code> passes them to the <code>Scene</code> instance, which takes ownership.</li>
</ul>
<p>Minimal code example is <a href="https://coliru.stacked-crooked.com/a/fbd879ab9d4beb69" rel="noreferrer">this</a>:</p>
<pre><code>#include <memory>
#include <utility>
class Interface
{
public:
virtual ~Interface() = 0;
};
inline Interface::~Interface() {}
class Foo : public Interface
{
};
class Bar : public Interface
{
};
class Scene
{
public:
void addObject(std::unique_ptr<Interface> obj);
// void addObject(std::shared_ptr<Interface> obj);
};
void Scene::addObject(std::unique_ptr<Interface> obj)
{
}
//void Scene::addObject(std::shared_ptr<Interface> obj)
//{
//}
int main(int argc, char** argv)
{
auto scn = std::make_unique<Scene>();
auto foo = std::make_unique<Foo>();
scn->addObject(std::move(foo));
// auto bar = std::make_shared<Bar>();
// scn->addObject(bar);
}
</code></pre>
<p>Uncommenting the commented lines results in:</p>
<pre><code>error: call of overloaded 'addObject(std::remove_reference<std::unique_ptr<Foo, std::default_delete<Foo> >&>::type)' is ambiguous
scn->addObject(std::move(foo));
^
main.cpp:27:6: note: candidate: 'void Scene::addObject(std::unique_ptr<Interface>)'
void Scene::addObject(std::unique_ptr<Interface> obj)
^~~~~
main.cpp:31:6: note: candidate: 'void Scene::addObject(std::shared_ptr<Interface>)'
void Scene::addObject(std::shared_ptr<Interface> obj)
^~~~~
</code></pre>
<p>Uncommenting the shared and commenting the unique stuff also compiles, so I take it the problem is, like the compiler says, in the overload. However I need the overload as both these types will need to be stored in some kind of collection, and they are indeed kept as pointers to base (possibly all moved into <code>shared_ptr</code>s).</p>
<p>I'm passing both by-value because I want to make clear I'm taking ownership in <code>Scene</code> (and upping the reference counter for the <code>shared_ptr</code>s). Not really clear to me where the issue lies at all, and I couldn't find any example of this elsewhere.</p>

Why does SyntaxNode.ReplaceNode change the SyntaxTree options? : <p>I'm trying to replace nodes within a syntax tree in Roslyn, and it's just about working, but with an annoyance which feels it <em>shouldn't</em> be a problem.</p>
<p>The syntax tree is generated from a script, and I want the result to be a script-based syntax tree too - but for some reason, replacing a node in the tree creates a new syntax tree with changed options: the <code>Kind</code> becomes <code>Regular</code> instead of <code>Script</code>. That's fixable with <code>SyntaxTree.WithRootAndOptions</code> but it feels like I'm doing something wrong if I need to call that.</p>
<p>Sample program:</p>
<pre><code>using Microsoft.CodeAnalysis;
using Microsoft.CodeAnalysis.CSharp;
using Microsoft.CodeAnalysis.CSharp.Scripting;
using Microsoft.CodeAnalysis.CSharp.Syntax;
using Microsoft.CodeAnalysis.Scripting;
using System;
using System.Linq;
class Program
{
static void Main(string[] args)
{
Script script = CSharpScript.Create("Console.WriteLine(\"Before\")",
ScriptOptions.Default.AddImports("System"));
var compilation = script.GetCompilation();
var tree = compilation.SyntaxTrees.Single();
var after = SyntaxFactory.LiteralExpression(
SyntaxKind.StringLiteralExpression,
SyntaxFactory.Literal("After"));
var root = tree.GetRoot();
var before = root.DescendantNodes().OfType<LiteralExpressionSyntax>().Single();
var newRoot = root.ReplaceNode(before, after);
var fixedTree = newRoot.SyntaxTree.WithRootAndOptions(newRoot, tree.Options);
Console.WriteLine(newRoot); // Console.WriteLine("After")
Console.WriteLine(tree.Options.Kind); // Script
Console.WriteLine(newRoot.SyntaxTree.Options.Kind); // Regular
Console.WriteLine(fixedTree.Options.Kind); // Script
}
}
</code></pre>
<p>(Output is in comments.)</p>
<p>Is this workaround actually correct, or is there some different way I should be replacing the node in the tree?</p>

SwiftUI: NavigationLink not working if not in a List : <p>I guess it might be a bug in beta 3 as the NavigationView is all broken. But a view like that:</p>
<pre><code>struct GenreBadge : View {
@EnvironmentObject var store: Store<AppState>
let genre: Genre
var body: some View {
NavigationLink(destination: MoviesGenreList(genre: genre).environmentObject(store)) {
RoundedBadge(text: genre.name)
}
}
}
</code></pre>
<p>is not triggering any push in the navigation stack. The view doens't seems interactive at all. If anyone found a workaround would be good, unless Apple is documenting this behaviour I would consider it broken until beta 4. </p>
