Is there an algorithm or hash to splits groups into 2, for A/B Testing?
We have customerIds, 1-5000. originally thinking of using Even/Odd, Mod %2. Are there any other algorithms available? Just curious, currently using Java Spring Boot.

I want to make an arraylist that has random numbers and make it in order from least to greatest.
How do I do this?
Try using the

please help me this algoritma
If the pattern of the directory of your images is always the same you can incorporate a regular expression to parse everything after EasyImage/.
You can use:
([^\/]+)(?=$)
It matches any character after the last slash.

I want a program for printing numbers in below format in java.
for(int i=0,r=1;i<h.length/2;) {
//System.out.println(h[i]);
for(int j=i;j<r;j++) {
System.out.print(h[j]);
}
System.out.println("");
r=r+2;
}
The expected output should be
1
24
356
System.out.println("1\n\n24\n\n356");
</sarcasm>
more information is needed (what is your exact problem? what do you want to achieve? input -> outcome)
what have you tried and where exactly are you stuck.
Edit your question and i edit my answer ;)

Airthematic operation on Big numbers up to 30 to 40 digits long, some of the related material on internet is not really related. any idea how can we do this.
It's right under your nose, in the standard Java API.
You should use BigInteger or BigDecimal for this purpose.
