I have tested it for many times,but I still got wa1,please help me
this is my program:
#include <iostream>
#include <fstream>
#include <string>
#include <cstring>
#include <sstream>
using namespace std;

int dui[10000],flag[11];
int zhan[20][2],zuo=0,you=1;
char wei[4]={'R','T','L','B'};
int head=0,tail=1;
string ord[20];
void init()
{
stringstream sn;
int i;
sn<<pan;
sn>>n;
for(i=1;i<=n;i++)
fin>>bla[i][0]>>bla[i][1];
}
void solve()
{
int fang,x,y,i;
fout<<bla[1][0]<<' '<<bla[1][1]<<endl;
dui[head]=1;

break;
}
}
