# scoresSpecial challenge

Hi,

i am working one below challenge
http://codingbat.com/prob/p140485

i was not clear on below description

Given two arrays, A and B, of non-negative int scores. A "special" score is one which is a multiple of 10, such as 40 or 90. Return the sum of largest special score in A and the largest special score in B. To practice decomposition, write a separate helper method which finds the largest special score in an array. Write your helper method after your scoresSpecial() method in the JavaBat text area.

scoresSpecial([12, 10, 4], [2, 20, 30]) → 40
scoresSpecial([20, 10, 4], [2, 20, 10]) → 40
scoresSpecial([12, 11, 4], [2, 20, 31]) → 20

actually, the answer is fully given there, apart from actually giving out the code itself.

Good luck to you in your mysterious and futile mission.

something like above?

something like above. Above passes all tests.
Any improvements or alternate approaches?

more refactored to helper method as above.

Commented:
That is good. I think you are improving.  You could clean it up to make it more readable.
``````public int scoresSpecial(int[] a, int[] b) {
return (scoresUtil(a) + scoresUtil(b));
}
public int scoresUtil(int[] x){
int largest = 0;
for(int i = 0; i < x.length; i++){
if(x[i]%10 == 0 && largest < x[i]){
largest = x[i];
}
}
return largest;
}
``````

I think the code is ok and complete, at least I see nothing missing

Commented:
Very funny - you deleted my code for being "complete" (full was the term used). So what's the difference now?

@krakatoa,
So what's the difference now?
The difference is that I was just rewriting gudii9 code that he posted at

Commented:
The point is both your code and mine passed all the tests, and you made no more attempt to get him to iron out his mistakes and recode it than I did - so imho, the situation is still not kosher.

i like naming largest and your code is more refined.
