Haskell translation

Quite tricky kata although it doesn't seem at first.

goal is the target sum.

C++ Translation

nice bro, it was a more harder 7 kyu ngl

The message is telling you your solution returned 2 for that input. The correct answer is, indeed, 1.

I really not understand where is the mistake, is only 1 change from negative to positive arr[3-4]

Input: [-2,-2,-5,-4,5,2,0,6,0]
Assertion: expected 2 to equal 1

I'm a beginner. I had to spend 2 hours on this kata, it was hell for me, but I'm glad I got through it.

I thought this kata is very hard to be 7kyu. I finish it but wasn't so easy

I don't see anywhere in the description that says 0 is considered positive. However, it may be implicitly implied otherwise to be non-negative... unless you intend to employ -0. So, the sign must change anyway if a negative number goes to a zero.
