ACM多组测试怎么输入啊每组多行？

int n

while((scanf("%d",&n))==1){

int a[6][6]

for(int i=0i<ni++)

for(int j=0j<nj++)

scanf("%d",&a[i][j])

}

#include<iostream>

#include<stdio.h>

#include<math.h>

using namespace std

int a[100001]

int main()

{

int n,m

while(scanf("%d",&n)!=EOF)

{

int i,j,x,t

m = 0

for(i=0i<ni++)

{

scanf("%d",&x)

if(x == 1){

scanf("%d",&t)

for(j = m-1j>=0j--)

if(a[j]>t)

a[j+1] = a[j]

else break

a[j+1] = t

m ++

}

else if(x == 2){

if(m%2)printf("%.1lf\n",a[m/2]*1.0)

else printf("%.1lf\n",(a[m/2]+a[m/2-1])/2.0)

}

}

}

return 0

}
