done! thanks for also providing the solution!

added tests for checking duplication

ah i see , i will add that now. Thanks!

can you please provide an example? also should i add more test cases for duplication cases?

I think that the current description is good. It is important to explain why the given powers are close to integers. My approach is not very obvious: Other solutions do not use it.

Approved

I added one example with 5 steps.

It should be clear that in order to get from step 1 to 5, there should be at least 4 instructions.

from say step 2 to 5 or 1 to 4, there should be at least 3 instructions.

from 1 to 3, 2 to 4, 3 to 5, 2 instructions.

you get my point? The graphs that I made have multiple examples within that are "subarrays" of the example with most instructions.

either way, the suggestion won't be implemented, as it would invalidate too many results on an approved kata

for me, it was not clear at all from the description, which sequences to include and which to discard

.

Approved

perhaps the restrictions aren't tight enough

resolved

Well, there's no happiness without suffering; congrats on solving!

Though you're making me question whether I should add a barrier against hardcoding...
