题解 | 二维数组求和

public class Main {
    public static void main(String[] args) {
        int[][]  arr = {{11,33,55},{22,44,66,88},{131,214,315,146},{928,827,726,625},{424,525}};
        int sum=add(arr);
        System.out.println(sum);
    }

    public static int add(int[][] arr) {
        int sum=0;
        for(int i = 0;i<5;i++){
            for(int j = 0;j<arr[i].length;j++){
                sum = sum + arr[i][j];
            }
        }
       
        

        return sum;
    }
}

内部嵌套不能够用硬嵌套
