C++

#include <string>
#include <vector>

using namespace std;

int solution(vector<int> a, vector<int> b) {
    int answer = 0;

    for(int i=0; i<a.size(); i++){
        answer += a[i] * b[i];
    }

    return answer;
}

JavaScript

function solution(a, b) {
  var answer = 0;

  for (let i = 0; i < a.length; i++) {
    answer += a[i] * b[i];
  }

  return answer;
}
