注意事项:

参考代码:

import java.util.Scanner;

public class Main{

/**

* @param args

*/

public static void main(String[] args) {

// TODO Auto-generated method

Scanner sc=new Scanner(System.in);

int n=sc.nextInt();

int a[][]=new int[n][n];

int i,j;

for(i=0;i<n;i++)

for(j=0;j<n;j++)

a[i][j]=sc.nextInt();

int count1=0,count2=0;

for(i=0;i<n;i++)

{

for(j=0;j<n;j++)

{

if(a[i][j]<=50)

{

count1++;

if(i==0||i==n-1||j==0||j==n-1)

count2++;

else

{

if(a[i-1][j]>50||a[i+1][j]>50||a[i][j+1]>50||a[i][j-1]>50)

count2++;

}

}

}

}

System.out.println(count1+" "+count2);

}

}
