肿瘤面积利用二位数组求解

解题思路:

注意事项:

参考代码:

import java.util.Scanner;

public class Main {

public static void main(String[] args) {

// TODO Auto-generated method stub

Scanner sc=new Scanner(System.in);

int n=sc.nextInt();

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

int i,j;

boolean flag=false;

int i1=0,j1=0,i2=0,j2=0;

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

{

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

{

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

if(a[i][j]==0)

{

if(!flag)

{

flag=true;

i1=i;

j1=j;

}

else{

i2=i;

j2=j;

}

}

}

}

System.out.println((i2-i1-1)*(j2-j1-1));

}

}
