C里那个好乱`!看不懂`` 还是自己弄出来了!!

哈哈``

public class Test9gongtu {
    
    public static  void main(String args[]){
        int a[][]=new int[5][5];
              for(int i=0 ;i<a.length;i++){
                  for(int j=0;j<a[i].length;j++){
                      a[i][j]=0;
                  }
              }
              
              int i,j;
              int n=5;
              int per_i;
              int per_j;
              a[0][n/2]=1;
              i=0;
              j=n/2;
              for(int k=2;k<=n*n;k++){
                  per_i=i;
                  per_j=j;
