若有以下程序
#include＜stdio.h＞
#define N 4
void fun(int a[][N],int b[],int flag)
int i,j;
for(i=0;i＜N;i++)
b[i]=a[i][0];
for(j=1;j＜N;j++)
if(flag(b[i]＞a[i][j]):(b[i]＜a[i][j]))
b[i]=a[i][j];
main()
int x[N][N]=1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,y[N],i;
fun(x,y,1);
for(i=0;i＜N;i++)printf("%d,,y[j]);
fun(x,y,0);
for(i=0;i＜N;i++)printf("%d,",y[i]);
printf("\n");
则程序的输出结果是______。
A．1,5,9,13,4,8,12,16，
B．4,8,12,16,1,5,9,13,
C．1,2,3,4,13,14,15,16,
D．13,14,15,16,1,2,3,4,
