HJ83 二维数组操作

法一

import java.util.Scanner;
public class Main {public static void main(String[] args) {Scanner in = new Scanner(System.in);// 注意 hasNext 和 hasNextLine 的区别while (in.hasNextInt()) { // 注意 while 处理多个 caseint m = in.nextInt();int n = in.nextInt();int[][] a = new int[m][n];System.out.println((m > 9 || n > 9) ? -1 : 0);int x1 = in.nextInt();int y1 = in.nextInt();int x2 = in.nextInt();int y2 = in.nextInt();System.out.println(((Math.max(x1, x2) >= m) ||(Math.max(y1, y2) >= n)) ? -1 : 0);int x = in.nextInt();System.out.println((x >= m || (m + 1) > 9) ? -1 : 0);int y = in.nextInt();System.out.println((y >= n || (n + 1) > 9) ? -1 : 0);x = in.nextInt();y = in.nextInt();System.out.println((x >= m || y >= n) ? -1 : 0);}}
