-12 + (-18) = -30; the target is '6 - (-12) = 18' or '6 - (-18) = 24';

There is quite good solution, but it isn't consider values such as:

• for s = 6
• v1 = -12
• v2 = -18

So, 6 can be found by (-12 - -18) for example...

Practice. Don't listen to negative responses.

no bro :(

Your problem comes from the concept of proximity. The description says that we sould return the pair with the lowest last element's index. It means that in [10, 5, 2, 3, 7, 5] the answer is [3,7]. In [10, 5, 2, 3, 5, 7] the answer is [5,5] because the last 5 has an index lower than 7.

If you see what I have been trying to do in 3 days, you will advice me to quit.

Well, this one is more inspiring. For the kata, the algorithm complexity of solution can not be reduced. However this trick is somehow better than doing int comparison (as I once did), let alone adding up two numbers each time. On the other hand, utilizing the set type also involves consideration of the feature of python language, which is good.

It should be parsed from left side and that means [4,3] shoud be the first result instead of [5,2]. But maybe the description is not clear enough for me :-)

I think I didn't understand what I had to do in this Kata because if this is the solution you're only checking the next and guesses the answer but it doesn't really check if that was the best or correct answer.

In the example:

[10, 5, 2, 3, 7, 5], 10

If I move the last five one step back the result is [5,5].

But the real answer is still [3,7] because the difference in proximinity is (5 - 4) = 1 vs (5 - 1) = 4.

Not convinced by this answer at all it just hacks the tester.

Wow, I didn't expect the solution to this kata could be that simple. Amazing. I stand in owe, bowing to you Master.

thanks
