题目描述：

This time, you are supposed to find A+B where A and B are two matrices, and then count the number of zero rows and columns.

输入：

The input consists of several test cases, each starts with a pair of positive integers M and N (≤10) which are the number of rows and columns of the matrices, respectively. Then 2*M lines follow, each contains N integers in [-100, 100], separated by a space. The first M lines correspond to the elements of A and the second M lines to that of B. The input is terminated by a zero M and that case must NOT be processed.

输出：

For each test case you should output in one line the total number of zero rows and columns of A+B.

先输入矩阵行和列的数，再列出2个矩阵的数字，然后矩阵相加，算出行数都是零和列数都是零的总和。

Java

import java.util.ArrayList;

import java.util.List;

import java.util.Scanner;

public class Main {

    public static void main(String[] args) {

        List<Integer> mList = new ArrayList<Integer>();

        Scanner cin = new Scanner(System.in);

        int rows;

        while ((rows = cin.nextInt()) != 0) {

            int columns;

            int totalTmp = 0;

            int total = 0;

            columns = cin.nextInt();

            int[][] arrays1 = new int[rows][columns];

            int[][] arrays2 = new int[rows][columns];

            for (int i = 0; i < rows; i++) {

                for (int j = 0; j < columns; j++) {

                    arrays1[i][j] = cin.nextInt();

                }

            }

            for (int i = 0; i < rows; i++) {

                for (int j = 0; j < columns; j++) {

                    arrays2[i][j] = cin.nextInt();

                    totalTmp = totalTmp | (arrays1[i][j] + arrays2[i][j]);

                }

                if (totalTmp == 0) {

                    total++;

                }

                totalTmp = 0;

            }

            for (int colum = 0; colum < columns; colum++) {

                for (int row = 0; row < rows; row++) {

                    totalTmp = totalTmp

                            | (arrays1[row][colum] + arrays2[row][colum]);

                }

                if (totalTmp == 0) {

                    total++;

                }

                totalTmp = 0;

            }

            mList.add(total);

        }

        for (int num : mList) {

            System.out.println(num + "");

        }

    }
