I got it!
I misunderstand the kata.. lol

thanks Sensei!

Woops, I take that back. It looks fine. 11 should be the correct answer here. So the number in the 11th slot is -6051.

• The numbers to the left of -6051 are [-1286,-1009,-7762,6264,9804,705,-1636,-8682,8837,-2332,8469]. These numbers added together equal 11372.
• The numbers to the right of -6015 are [-9292,935,19729]. These numbers added together equal 11372.

Both sides are equal at position 11.

looks like you may be editing the variables that are sent to you. If you wouldnt mind posting your code below, I can help you out. Just let me know what language it is in.

I can't find out why this result is expected 11..

The failed array was: -1286,-1009,-7762,6264,9804,705,-1636,-8682,8837,-2332,8469,-6051,-9292,935,19729
Expected: 11
But was: -1
