总是WA..#include <fstream>
using namespace std;
void main(){
int Stan=0,Ollie=0;
int x[200000],y[200000],cx,cy;
int len;
ifstream finput("input.txt");
finput>>len;
for(int i=1;i<=len;i++){
finput>>x[i]>>y[i];
}
finput.close();
cx=x[(len+1)/2];
cy=y[(len+1)/2];
for(i=1;i<=len;i++){
if((x[i]>cx&&y[i]>cy)||(x[i]<cx&&y[i]<cy))
Stan++;
else if((x[i]>cx&&y[i]<cy)||(x[i]<cx&&y[i]>cy))
Ollie++;
}
ofstream foutput("output.txt");
foutput<<Stan<<' '<<Ollie;
foutput.close();
}
哪里出问题了啊?
