코딩테스트 연습 - 행렬의 곱셈

public class Solution {
    public int[,] solution(int[,] arr1, int[,] arr2) {        
        int[,] answer = new int[arr1.GetLength(0), arr2.GetLength(1)];

        for (int i = 0; i < arr1.GetLength(0); i++)
            for (int j = 0; j < arr2.GetLength(1); j++)
                for (int x = 0; x < arr1.GetLength(1); x++)
                    answer[i, j] += arr1[i, x] * arr2[x, j];

        return answer;
    }
}
