creating array with non constant parameters : I'm currently working on an assignment where I must find a way to output the longest common sub-sequence of two strings. In all of the other places I have found implementations of this code, they all share one similarity which is, multiple arrays are initialized with non constant variables which I had always learned was not allowed, and the program does not compile. Is there some way around this rule or is there something I am missing?
#include <iostream>
#include <algorithm>
#include <vector>
using namespace std;
//Prints the Longest common subsequence
void printLCS(char *s1, char *s2, int m, int n);
/* Driver program to test above function */
int main()
{
char s1[] = "ABCBDAB";
char s2[] = "BDCABA";
printLCS(s1, s2, strlen(s1), strlen(s2));
return 0;
}
void printLCS(char *s1, char *s2, const int m, const int n)
{
int L[m + 1][n + 1];
//Building L[m][n] as in algorithm
for (int i = 0; i <= m; i++)
{
for (int j = 0; j <= n; j++)
{
if (i == 0 || j == 0)
L[i][j] = 0;
else if (s1[i - 1] == s2[j - 1])
L[i][j] = L[i - 1][j - 1] + 1;
else
L[i][j] = max(L[i - 1][j], L[i][j - 1]);
}
}
//To print LCS
int index = L[m][n];
//charcater array to store LCS
char LCS[index + 1];
LCS[index] = '\0'; // Set the terminating character
//Stroing characters in LCS
//Start from the right bottom corner character
int i = m, j = n;
while (i > 0 && j > 0)
{
//if current character in s1 and s2 are same, then include this character in LCS[]
if (s1[i - 1] == s2[j - 1])
{
LCS[index - 1] = s1[i - 1]; // Put current character in result
i--; j--; index--; // reduce values of i, j and index
}
// compare values of L[i-1][j] and L[i][j-1] and go in direction of greater value.
else if (L[i - 1][j] > L[i][j - 1])
i--;
else
j--;
}
// Print the LCS
cout << "LCS of " << s1 << " and " << s2 << " is " << endl << LCS << endl;
}
Specifically the declarations for array L and array index.
Sorry if this code is a mess I don't really post here. Any help would be greatly appreciated.

Push Notifications over WiFi : <p>I noticed by in Boingo's Wi-Finder iOS app, that the app pushes a notification to the user once he reaches an access point regestered at Boingo's database. The notification tells the user that he can access the wifi network.</p>
<p>How is that done iOS?</p>

Please explain this line of javascript code : <pre><code>jBox.prototype.position = function (options)
{
// this line
!options && (options = {});
}
</code></pre>
<p>In conventional programming boolean statements are used in if else statements.
What does !options && (options = {}); translate too?</p>
<p>options is a json or array. What does !options mean?</p>
<p>options = {} is assigning a empty json to variable options, how does it return a boolean value to be used with &&.</p>

Used List<MapPdf> to var : I have a program that I used a variable of type List<MapPdf> that I will detach in variables when filling I would like to have the possibility to use it another time but I did not have the right to identify it again as <MapPdf>
public static void Create(List<MapPdf> pps, Saison s, Agence agence)
{
foreach (var pelerins in grouped)
{
if (string.IsNullOrEmpty(pelerins.Key) || pelerins.Count() <= 0)
break;
if (writer.PageEvent == null)
{
writer.PageEvent = new Header_List()
{
travel = ctx.Travels.Include("Transport").First(v => v.UniqueId == pelerins.Key),
travelretour = ctx.Travels.Find(pelerins.First().UniqueIdRetour),
Agence = agence,
CountAllPelerin = pelerins.Count().ToString(),
CountFeminin = pelerins.Count(x => x.Sexe == PelerinSexe.Feminin).ToString(),
CountMasculin = pelerins.Count(x => x.Sexe == PelerinSexe.Masculin).ToString(),
NomGroupe = pelerins.First().Groupe,
NumeroDoc = writer.PageNumber
};
}
}
}
And i want to use pls as a List<MapPdf> when i used in another function when it is of this declaration
CreateFr(pls, false, cb, s);
I used List < MapPdf > pls = pelerins.ToList(); but it does not work

Copy and paste value X amount of times : I'm currently working on a project on VBA that requires multiple manipulation on data.
I need to create a macro that copies the information from cell "Q2" and pastes it on cell "A2", "B2","C2" and "D2".
From there it needs to do the same with the information of cell "Q3" and paste it on "E2" and so on until there is no further data on "Q".
At the moment it needs to paste the data a total of 4 times, but it needs to be modified later on for it to be 2 or 3 times.
Any idea on how to make this?
Thanks!

How to create Fragment witch shows element clicked on RecyclerView? : I'm new at Android so maybe I'm just lack of understanding how things work. So what I have right now is RecyclerView of five elements. Each of them contains figure of different shape, different fruit name and different color bar. What I seek is to create Fragment which would show some background color, figure and fruit name inside that figure, depending on what Recyclerview element user clicks. How can I do that?
That's my **MyAdapter.java**
public class MyAdapter extends RecyclerView.Adapter <MyAdapter.MyViewHolder> {
Context context;
ArrayList<Information> data;
public MyAdapter(Context context, ArrayList<Information> data) {
this.context = context;
this.data = data;
}
@Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.custom_row,parent,false);
MyViewHolder holder = new MyViewHolder(view);
return holder;
}
@Override
public void onBindViewHolder(final MyViewHolder holder, final int position) {
holder.textView.setText(data.get(position).title);
holder.relativeLayout.setBackground(context.getResources().getDrawable(data.get(position).shape));
holder.textView2.setBackground(context.getResources().getDrawable(data.get(position).color));
}
@Override
public int getItemCount() {
return data.size();
}
class MyViewHolder extends RecyclerView.ViewHolder {
TextView textView,textView2;
RelativeLayout relativeLayout;
public MyViewHolder(View itemView) {
super(itemView);
textView = (TextView) itemView.findViewById(R.id.txt_view);
relativeLayout = (RelativeLayout) itemView.findViewById(R.id.img_view);
textView2 = (TextView) itemView.findViewById(R.id.textView);
}
}
}
**MyActivity.java**
public class MyActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my);
RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recycler_view);
MyAdapter adapter = new MyAdapter(this, Data.getData(this));
recyclerView.setAdapter(adapter);
recyclerView.setLayoutManager(new GridLayoutManager(this,1));

sh: 1: Syntax error: "(" unexpected python : I'm executing an awk which looks like this.
`awk '{if(l1){print ($2-l1)/1024" kB/s",($10-l2)/1024" kB/s"} else{l1=$2; l2=$10;}}' <(grep eth0 /proc/net/dev) <(sleep 1; grep eth0 /proc/net/dev)`
and I always got the `sh: 1: Syntax error: "(" unexpected`
I tried writing it as a .sh file, and tried the different shebang lines.
I need to create a script that will execute this. Somebody ? please, thanks

The return value from the typeof operator is always one of six (seven as of ES6!) string values. That is, typeof "abc" returns "string", not string.
I am unable to understand diffence b/w "string" and string.

Why the answer is 26 for this code? : public class Program
{
public static void main(String[] args) {
int x=1;
for(;x<6;x++) x=x*x;
System.out.printf("%d",x);
}
}
I have been learning java for months. What I'm amazed I have found this kind of a set question in sololearn and I have proved myself the answer is 26.
I understand the normal for loop how it works, but I don't understand this kind of format.

django QueryDict only returns the last value of a list : <p>Using django 1.8, I'm observing something strange.
Here is my javascript:</p>
<pre><code>function form_submit(){
var form = $('#form1_id');
request = $.post($(this).attr('action'), form.serialize(), function(response){
if(response.indexOf('Success') >= 0){
alert(response);
}
},'text')
.fail(function() {
alert("Failed to save!");
});
return false;
}
</code></pre>
<p>and here are the parameters displayed in views.py</p>
<pre><code>print request.POST
<QueryDict: {u'form_4606-name': [u''], u'form_4606-parents': [u'4603', u'2231', u'2234']}>
</code></pre>
<p>but I cannot extract the parents:</p>
<pre><code>print request.POST['form_4606-parents']
2234
</code></pre>
<p>Why is it just giving me the last value?
I think there is something wrong with the serialization, but I just cannot figure out how to resolve this.</p>

Does PHP have to go along with SQL? : <p>I have been researching Sql, Django, PhP,</p>
<p>I saw this one tutorial on creating a social network website and they were using SQL in conjunction with PHP. Is this always required? What does the PHP do for the SQL? I know it is a server side, but isn't Django as well?
So I can use Django/SQL instead of PHP/SQL?</p>

<p>and I want to push to the inner array the string below</p>

<p>the string above I got it from an array using array_shift</p>
<pre><code>$id = array_shift($_POST['updateIDs']);

auto generated value for primary key with primary numbers : I want to make auto generated value for primary key with primary numbers
for example I have this table where `id` is the primary key:
tags_table :
id | name
---------
2 | some_text
3 | some_text
5 | some_text
...
997| some_text
when ever new row inserted it will get the next primary number for the `id` .
**is** there a way to achieve this in mysql or any other RDBMS ? if so **how** ?

Using self join on a table to compare two fields based on a linked field in the same table : I have the following:
TableA
ID|DocumentType|DocumentCode|DocumentDate|Warehouse|RefecenceCode|
1 |DeliveryNote| DOC-001 | 2017-04-21 | 1 | NULL |
2 |Invoice | DOC-002 | 2017-04-21 | 2 | DOC-001 |
As you can see, the warehouse is different on each document and DOC-002 is related to DOC-001 through the information in `ReferenceCode` column (which means that was created starting from DOC-001 as a source document). It is supposed for the DOC-002 to have the same information but sometimes might be different and in this case, I was tried to create a query (I thing `self join` applies here) in order to check what information is different in the DOC-002 in this case compared to DOC-001, based on the reference code, but I couldn't managed to do it. If someone could give me a hand, I'll be very grateful. Thanks!

Why does iPhone layout look different in xCode and in Emulator : I've been developing a modified version of an iPad application, and try though I might, I've been unable to resolve the following issue.

I'm using a UITableView to display cells of information, however the cells have huge gaps between them in the iPad emulator.

If anyone has any ideas that I could try, I'd be happy to test out any different ideas to resolve the issue.

node.js - Loading html in a similar way to PHP : <p>I am learning Node.js for website development.<br>
Previously I could use PHP to include something like a navigation bar on every page, using <code><?php include('blah.php') ?></code>. This works in the same way of me just using the actual code on the page.<br>
My question is: is there any way to import HTML elements / pages from one page to another with JS / Node.js?<br>
Bearing in mind, PHP integrates directly with HTML in the same file, and Node.js does not integrate so seamlessly, so what I'm asking might be impossible.</p>

I want to continus display of button in wpf : In my application I have 4 button. If user will click on a button, that will disappear and remaining 3 still display.
The problem is that I don't want a control (button) gap between button.
I want remaining 3 should rearrange itself.
Which control I should use or how I can implement that. I am using MVVM in my application.

Simple Java programm runs slow on Windows 2008 Server : <p>Why is my simple Java programm runs quickly on my local computer and
too slow on Windows 2008 Server?</p>
<p>Programm code:</p>
<pre><code>public static void main(String[] args) {
long startTime;
long endTime;
long totalTime;
startTime = System.currentTimeMillis();
for (int a=1; a < 100000; a++) {
System.out.println("Checking");
}
endTime = System.currentTimeMillis();
totalTime = endTime - startTime;
System.out.println("TEST1 time:"+totalTime);
startTime = System.currentTimeMillis();
double sum = 0;
for (int a=1; a < 1000000; a++) {
int input = 100;
for(int counter=1;counter<input;counter++){
sum += Math.pow(-1,counter + 1)/((2*counter) - 1);
}
}
endTime = System.currentTimeMillis();
totalTime = endTime - startTime;
System.out.println("TEST2 time:"+totalTime+" pi="+sum);
}
</code></pre>
<p>Local computer output:</p>
<pre><code>Checking
Checking
Checking
Checking
TEST1 time:427
TEST2 time:7261 pi=787922.5634628027
</code></pre>
<p>Windows server output:</p>
