注意事项:

参考代码:

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
     Scanner scanner=new Scanner(System.in);
     int m=scanner.nextInt();
     int n=scanner.nextInt();
     int[][] nums=new int[m][n];
     for (int i = 0; i < m; i++) {
        for (int j = 0; j < n; j++) {
            nums[i][j]=scanner.nextInt();
        }
    }
     int x=scanner.nextInt();
     int y=scanner.nextInt();
     char s=scanner.next().charAt(0);
     int k=scanner.nextInt();
    for (int i = 0; i < k; i++) {
        if(nums[x][y]==0){
            switch (s) {
            case 'U':
                s='L';
                nums[x][y]=1;
                y--;
                break;
            case 'L':
                s='D';
                nums[x][y]=1;
                x++;
                break;
            case 'D':
                s='R';
                nums[x][y]=1;
                y++;
                break;
            case 'R':
                s='U';
                nums[x][y]=1;
                x--;
                break;
            }
          }else {
              switch (s) {
              case 'U':
                  s='R';
                  nums[x][y]=0;
                  y++;
                  break;
              case 'R':
                  s='D';
                  nums[x][y]=0;
                  x++;
                  break;
              case 'D':
                  s='L';
                  nums[x][y]=0;
                  y--;

                  x--;
                  break;
          }
          }
     }    
    System.out.println(x+" "+y);
  }
