What's the difference between the parts?

Thanks for this mind blowing challenge

No)

bravissimo!)))

There was a bug in example tests, I fixed it. After you reset the trainer (remember to back up your solution first!), you should be able to run example tests without problems now.

If there is still some other problem, please raise a separate issue.

yeah, can't solve this task without new test framework

Thanks, I realised there you have to assign double, not int or float in c++ to return correct answer

It means two things:

• Tests have a bug and present values incorrectly, and
• Your solution has a bug and returns values which are not exact enough. In your specific case, you should not need rounding at all.

I created an issue to fix tests, but you also need to fix your solution.

Excuse me, but, what's that means)))

Incorrect answer for:
a=Point{49.59295, -24.44708}
b=Point{26.14428, 5.185715}

Expected: equal to 37.7881 (+/- 1e-06)
Actual: 37.7881

It's difficult to tell exactly without seeing the code, but just by hearing what it was about, the solution does not sound right.

I changed to submit. Bug happen when I solved kata by turning a set back into a list and take slice

Does the bug happen with your current answer or did you change it?

unfortunately no, [20, 15] doesn't

I make all operations in return statement, and there is the bug, while slightly different descision is ok

But your solution passes?

I don't know why is it work so bad, but I make correct code, which I checked in visualisator and IDLE, but here it returns [20,15] not [20,17]

why?????????????????????????????????
