<p>When I debugged the program, I saw that when day = 1, month = 8, year = 1947, it jumped out of the loop.</p>
<p>I modified the code and debugged again, this time it jumped out when day = 31, month = 1, year = 1947.</p>

55,623,811 | confused with function int main ( int argc, char* argv[ ]) to read files and store in std::vector | i have to write a function where it receives 2 files as the command line argument (file1 file2) which the program reads in these files should be stored in two std:vector container
file 1 has 4 int values in each line representing a rectangles bottom point then top point eg 73 4 113 46 so x y x y i have to write a class for representing the rectangle which makes each rectangle an object of that class
file2 just contains list of areas 1 per line in int value.

Don't know why intent is getting null? BTW, onReceived called and works other things. Reminder is also coming. And I printed logs also, This: (Log.d("Test", "Alarm just fired") ;) is also printing.
Why?
Any help?
Looks like mostly code, so added some random article:
It looks like your post is mostly code; please add some more details
An article (with the linguistic glossing abbreviation art) is a word that is used with a noun (as a standalone word or a prefix or suffix) to specify grammatical definiteness of the noun, and in some languages extending to volume or numerical scope.
The articles in English grammar are the and a/an, and in certain contexts some. "An" and "a" are modern forms of the Old English "an", which in Anglian dialects was the number "one" (compare "on" in Saxon dialects) and survived into Modern Scots as the number "owan". Both "on" (respelled "one" by the Norman language) and "an" survived into Modern English, with "one" used as the number and "an" ("a", before nouns that begin with a consonant sound) as an indefinite article.
In many languages, articles are a special part of speech which cannot be easily combined[clarification needed] with other parts of speech. In English grammar, articles are frequently considered part of a broader category called determiners, which contains articles, demonstratives (such as "this" and "that"), possessive determiners (such as "my" and "his"), and quantifiers (such as "all" and "few").[1] Articles and other determiners are also sometimes counted as a type of adjective, since they describe the words that they precede.[2]
In languages that employ articles, every common noun, with some exceptions, is expressed with a certain definiteness, definite or indefinite, as an attribute (similar to the way many languages express every noun with a certain grammatical number—singular or plural—or a grammatical gender). Articles are among the most common words in many languages; in English, for example, the most frequent word is the.[3]
Articles are usually categorized as either definite or indefinite.[4] A few languages with well-developed systems of articles may distinguish additional subtypes. Within each type, languages may have various forms of each article, due to conforming to grammatical attributes such as gender, number, or case. Articles may also be modified as influenced by adjacent sounds or words as in elision (e.g., French "le" becoming "l'" before a vowel), epenthesis (e.g., English "a" becoming "an" before a vowel), or contraction (e.g. Irish "i + na" becoming "sna").

55,632,261 | How to pair sublists of (x,y) cell coordinates? | I have a list of 60 lists (representing 60 images). Each of these 60 lists contains 30 sublists, each sub-list corresponding to a cell's coordinates.
The goal is to track each cell's coordinates, in other words, to pair each sublist (cell) of the bigger list to all of the other sublists of each bigger list (the image). Thus, in the end, we shall obtain 60 lists: each list is a cell's coordinates over the 60 images. That way I can calculate each cell's speed.

55,633,137 | Assembly location for Razor SDK Tasks was not specified | <p>My project fails to build on a build server.
I recently added a new ASP.Net Core (2.2) MVC project with razor pages. The project and the rest of the solution target the .Net Framework 4.7.2.</p>
<p>In Visual Studio on my dev-machine this works fine, but the build server cannot build it. It shows this error.</p>
<blockquote>
<p>C:\Users\tfs-build.nuget\packages\microsoft.aspnetcore.razor.design\2.2.0\build\netstandard2.0\Microsoft.AspNetCore.Razor.Design.CodeGeneration.targets(161):C:\Users\tfs-build.nuget\packages\microsoft.aspnetcore.razor.design\2.2.0\build\netstandard2.0\Microsoft.AspNetCore.Razor.Design.CodeGeneration.targets(161,5):
Error : Assembly location for Razor SDK Tasks was not specified. The
most likely cause is an older incompatible version of
Microsoft.NET.Sdk.Razor, or Microsoft.NET.Sdk.Web used by this
project. Please target a newer version of the .NET Core SDK.</p>
</blockquote>
<p>I made my coworker install the <a href="https://dotnet.microsoft.com/download" rel="noreferrer">.Net Core SDK 2.2</a>, since I remembered installing that on the dev-machine to be able to create the project. But this did not help on the buildserver.</p>
<p>What could cause this? Why is the behaviour different from the development environment?</p>

It's a image/gif who appears first and it block my image.

55,634,812 | BiometricPrompt crashes on Samsung S9 with Face unlock | <p>I am using the new <a href="https://developer.android.com/reference/android/hardware/biometrics/BiometricPrompt" rel="noreferrer"><code>BiometricPrompt</code></a> API in Android P (API 28) in my application. (I am actually using it inside a wrapper based on <a href="https://github.com/anitaa1990/Biometric-Auth-Sample" rel="noreferrer">this project</a> so that it functions on older devices too, but that is not relevant to the question.) This is working very well on all devices I have tested, except for the Samsung S9 with face unlock.</p>
<p>Even though the stock Android version of <code>BiometricPrompt</code> currently only implements fingerprint authentication, Samsung appears to have extended it to support Face Unlock as well. When I trigger biometric authentication in my app, the "bottom sheet" pops up with a face icon (instead of the fingerprint icon shown on all other devices) and at the top of the screen some text appears that says "no face detected". (Note that the icon shown here is provided by the operating system, not by me, so it is obviously of Samsung's design.)</p>
<p>According to the documentation, the <code>BiometricPrompt</code> is only supposed to close itself and call my <code>onAuthenticationSucceeded</code> method if the authentication has been successful. According to <code>logcat</code>, it looks like it has been successful:</p>

55,643,527 | How to return int and string attributes in a single java method | I would like to return the values of all the attributes from the Baseballplayer class. The method that needs to do this must be the public string getBaseballPlayer(int i) method (because I need to reference this method inside getBaseballPlayers() to return all the values as an arraylist of strings) I'm having trouble doing this because all the attributes have different datatypes (int, string, Height).
Ive tried doing this
public String getBaseballPlayer(int i){
ArrayList <String> bArray = new ArrayList <String>();
bArray.add(getHometown());
bArray.add(getState());
bArray.add(getHighSchool());
bArray.add(getPosition());
however it only works for the string methods, and doesn't necessarily return the actual values but rather the get methods for each string attribute.
public class BaseballPlayer extends Player implements Table {
private int num;
private String pos;
public BaseballPlayer( int a, String b, String c, int d,
String e, String f, String g, Height h){
super(a,ft,in,c,d,e,f,ht);
num = a;
pos = b;
}
public BaseballPlayer(){}
//Returns the value of a specific attribute. The input parameter start
with 0 for the first attribute, then 1 for the second attribute and so
on.
//you can use getBaseballPlayer(int i) in getBaseballPlayers( ) with a for
loop getting each getBaseballPlayer(int i).
public String getBaseballPlayer(int i){
ArrayList <String> bArray = new ArrayList <String>();
bArray.add(getHometown());
bArray.add(getState());
bArray.add(getHighSchool());
bArray.add(getPosition());
return (bArray);
}
//Returns the value of all attributes as an ArrayList of Strings.
public ArrayList <String> getBaseballPlayers(){
}
I'm just looking for the simplest way to return each attributes value, then using that method return each value as an arraylist of strings in another method. | <java><arrays><methods><return> | 2019-04-12 02:12:23 | LQ_EDIT |

<p>If I try to use "str_replace", I can have different results as intended, but this gave me 2 problems. One is that if i try to replace the name, i also change the href, and if i have similar URL with "more slashes" it will change the match part, and leave the rest of the information.</p>
<p>In a database I have list of URL with a column that have names, and if the string match any row in the table I need to change the name accordingly and preserve the href. </p>

**Please don't mark this as duplicate, I tried many resources before I came here. I want a solution not go read this documentation either.**

if (selectedNode.value ==="Humalog"){

else {

This value needs to be put in the function below:
```javascript
function doTheMath(){
let carbIntake = getCurrentMeal();
let cbs = getCurrentBloodSugar();
let tbs = getTargetBloodSugar();
let br = getBasalRate();
let is = getInsulinStrength();
let dailyBasalRate = br * 24;
let gramsPerInsulin = 450 / dailyBasalRate;
let bolus = carbIntake / gramsPerInsulin;
if (cbs > tbs){
let correctionFactor = is / dailyBasalRate;
let correctionDose = (cbs - tbs) / correctionFactor;
bolus += correctionDose;
}
return bolus;
}
```
Everything else works minus the getInsulinStrength() function. Regardless of what the user chooses, it returns the same value.
I ADDED THE HTML CODE ~ just to make give more insight.

55,680,121 | How to represent mapping between two trees in Haskell? | <p>I'm trying to implement a tree-processing algorithm in Haskell, and (due to the fact this is my first Haskell program!), am struggling with the design of the data structures. Can any of the FP gurus out there lend a hand?</p>
<p>I'll start by describing the important characteristics of the algorithm, sketch out how I would approach this using an imperative language, and finish with the stumbling baby-steps I have made so far in Haskell.</p>
<h1>The problem</h1>
<p>I won't describe the full algorithm in detail, but the salient points are as follows:</p>
<ul>
<li>The algorithm operates on two rose trees, X and Y.</li>
<li>The first phase of the algorithm computes some derived properties for each node, based on its label and attributes, and those of its descendants.</li>
<li>These derived properties are used to compute a partial mapping between the two trees, such that a node in X may be associated with a node in Y and vice versa. Because the mapping is partial, any node in X or Y may either be mapped (i.e. have a partner the other tree), or alternatively may be unmapped.</li>
<li>The final phase of the algorithm optimises these mappings, via a sequence of operations which inspect parent / children / siblings of mapped nodes.</li>
</ul>
<p>The data structures must therefore have the following characteristics:</p>
<ul>
<li>Given a reference to a node, provide access the parent of that node, siblings of that node, and children of that node.</li>
<li>Given a node in an input tree, permit <em>annotation</em> of that node with additional information (derived properties, and an optional reference to a node in the other tree).</li>
</ul>
<h1>Sketch of an imperative solution</h1>
<p>If I was to implement this algorithm using an imperative language, the solution would look something like the following.</p>
<p>Let's assume that the starting point is the following definition of the input tree:</p>
<pre><code>struct node {
// Identifier for this node, unique within the containing tree
size_t id;
// Label of this node
enum label label;
// Attributes of this node
// An attribute can be assumed to be a key-value pair
// Details of the attributes themselves aren't material to this
// discussion, so the "attribute" type is left opaque
struct attribute **attributes;
size_t n_attributes;
// Pointer to parent of this node
// NULL iff this node is root
struct node *parent;
// Pointer to first child of this node
// NULL iff this node is leaf
struct node *child;
// Double-linked list of siblings of this node
struct node *prev;
struct node *next;
};
</code></pre>
<p>The pointers embedded in each node clearly support the up / down / left / right traversals required by the algorithm.</p>
<p>Annotation can be implemented by defining the following structure:</p>
<pre><code>struct algo_node {
// Pointer to input node which has been wrapped
struct node *node;
// Derived properties computed by first phase of the algorithm
// Details of the properties themselves aren't material to this
// discussion, so the "derived" type is left opaque
struct derived props;
// Pointer to corresponding node in the other tree
// NULL iff this node is unmatched
struct node *match;
};
</code></pre>
<p>The first phase of the algorithm constructs an <code>algo_node</code> for each <code>node</code> in each of the input trees.</p>
<p>Mapping from an <code>algo_node</code> to a <code>node</code> is trivial: follow the embedded <code>*node</code> pointer. Mapping in the other direction can be supported by storing <code>algo_node</code>s in an array, indexed by the <code>id</code> of the input node.</p>
<p>This is of course just one possible implementation. Many variations are possible, including</p>
<ul>
<li>Abstracting the children linked list behind a <code>list</code> or <code>queue</code> interface, rather than storing three raw pointers</li>
<li>Instead of associating the input tree with the algorithm tree via indices, encode parent / child / sibling relationships directly in <code>struct algo_node</code></li>
</ul>
<h1>Moving to Haskell</h1>
<p>Let's start with the following definition of the input tree:</p>
<pre><code>data Tree = Leaf Label Attributes
| Node Label Attributes [Tree]
</code></pre>
<p>Augmentation of each node with an id can be achieved as follows:</p>
<pre><code>data AnnotatedTree = Tree Int
addIndex :: Int -> AnnotatedTree -> (AnnotatedTree, Int)
indexedTree = addIndex 0 tree
</code></pre>
<p>Similarly, we can write a function which computes derived properties:</p>
<pre><code>data AnnotatedTree = Tree DerivedProperties
computeDerived :: DerivedProperties -> AnnotatedTree -> (AnnotatedTree, DerivedProperties)
derivedTree = computeDerived DefaultDerived tree
</code></pre>
<p>The above snippets can be adjusted with little work, such that <code>AnnotatedTree</code> contains both the index and the derived properties.</p>
<p>However, I don't know where to begin with representing mappings between the two trees. Based on some reading, I have some half-baked ideas ...</p>
<ul>
<li>Define <code>AnnotatedTree</code> to contain a path from the root of the other tree to the mapped node - encoded as a list of indices into each successive children list, <code>[Integer]</code>
<ul>
<li>Use a zipper (of which I currently have a fairly loose understanding) to access the mapped node (or its parent / children / siblings) via the path</li>
<li>Or perhaps use a lens (... of which I have an even less clear understanding!) to do the same</li>
</ul></li>
<li>Define <code>AnnotatedTree</code> to contain a reference to the mapped node directly, as a <code>Maybe Tree</code>
<ul>
<li>But then I don't see a way to walk to parent / siblings of the mapped node</li>
</ul></li>
</ul>
<p>... but I could really do with some guidance on which (if any) of these are worth pursuing.</p>
<p>Any help would be much appreciated!</p>

55,681,705 | How to remove duplicate categories from dataframe | I am trying to calculate the total number of companies associated with each active investor.
'df' represents my original dataframe, in which the 'active_investors' column displays a list of active investors for each company listed. For example, one row might contain Company A, listing investors 1,2,3,4.
What I am trying to do is split the dataframe such that it displays company A as four separate rows i.e. for each investor 1, 2, 3 and 4.
So far, I have the following code:
```
#Separate names of investors for each company
df1 = df %>% separate_rows(active_investors, sep = ",")
#Total number of companies each investor has invested in
investor = aggregate(data.frame(count = df1$company_name), list(active_investors = df1$active_investors), length)
```
The problem is that some investors are listed twice i.e. the same investor name, but are listed as two separate investors. I am unsure how to compile the frequencies (i.e. total companies the investor has invested in) such that these duplicates are removed. | <r><dataframe><dplyr><tidyr> | 2019-04-15 01:51:34 | LQ_EDIT |
