- Java

class Solution {
    public int solution(int[] ab, boolean[] signs) {
        int answer = 0;
        for(int i=0;i<ab.length;i++){
            if(signs[i])
                answer+=ab[i];
            else
                answer-=ab[i];
        }
        return answer;
    }
}

 

- Ruby

def solution(absolutes, signs)
    answer = 0
    for i in 0..(signs.size-1)
        if signs[i]==true
            answer=answer+absolutes[i]
        else
            answer=answer-absolutes[i]
        end
    end
    return answer
end
