Made some adjustments and approved.

See the new description

Okey

The description still does not say it expects an array of AP numbers, even though the example assumes you do, but without context it makes no sense why 15(7+8) is part of the answer for start=7 but 27(10+17) is not.

11, 13, 17, 19, 23, 29 are natural numbers so they can't be divided any way.

Every integer >0 is a natural number. Did you mean something like regular prime numbers?

Changed, take a look.

I have found this kata on the List of Java Kata to Update. I updated it to Java 17, changed /home/codewarrior/solution.txt to /workspace/solution.txt and I have also updated the test to JUnit5.

Take a look to the Fork, I have done my best.

• the case start=1 has to be present in the fixed/sample tests (with appropriate output)
• it's not said in the description how the start and end values are guaranteed (or not) to be: always <= ? alwys < ? no guarantee?

• the ref solution is wrong:

  1->8732
  array lengths differ, expected: <185> but was: <0>
  

if 1 is in the range, all numbers are divisbile by it => no coprime numbers

• the test constraints aren't given: how many tests? typical values for start and end?
• missing performance tag (but I suspect the constraint isn't properly enforced

Your example just adds more confusion I'm afraid.

• what are natural numbers?
• why add start +1 in example, not in other examples in the description?

Added new description with a step to step example

Added

Changed

The result is the set of numbers that can be decomposed from the sum of two prime numbers, considering the provider number (start param) and the next one (start+1) as primes, and all numbers smaller than the provided one are not.

The result is the set of prime (in the problem definition) numbers that can be decomposed from the sum of two distinct prime numbers. These should be in the problem description.(not true for start 0 or 1, but is the answer for every number greater than that)

All test inputs are going to be > 0.

There are cases where the random tests test for start = 0

This should have a performance tag.

I have no idea how could this problem work for start 0 or 1, maybe put one of them in the sample tests?

The task seems really confusing.

It would help a lot if you showed how 3, 50 corresponds to [7, 11, 17, 23, 41, 47] or some smaller toy example if that's too complicated.

It is still extremely unclear how the list of numbers are derived. You definitely need to provide a step-to-step example showing how it is derived.
