what if the char value is equal to 5 and your code will follow into else condition, I think it is better to use else if instead

No, it will fail with an ArrayIndexOutOfBoundsException.

adding int to a string directly for a pythonic guy was quite interesting

I solved this the same way except i converted the numberString.charAt(i) to an int before using it in the if statment and used the 5 as an int. I did not think that it would know what to do with the 5 as a char. Clearly I did not need to do that. I guess my question is how does java know?

Hi,

I'd advise you to stop "messing" with the beta process, unless you wanna your account locked.

Thx.

Print the input and you should see why they fail.

I tried indices as well, but didn't work anyway

My guess is as good as yours (haven't solved the kata). But I think the sum of those indices is the answer.

Don't open another issue if it is about the same problem.

I asked too :)

tf is 11 ?

where did exactly 11 come from in this part?
arr = [17, 12, 5, 6, 13, 3] where length is 6.
solution says:
this would return 7 due to
(170 + 52 + 134 + 35) / 11 = 7.
what is 11? shouldn't it be (170 + 52 + 134 + 35) / 4?
arr length is 6, primes length is 4, the only match i found is
5 + 4 + 2 + 0 = 11 (indexes)
