rt，刚刚有人说很难卡。

#include<cstdio>
#include<ctime>
#include<cstdlib>
using namespace std;
int main() {
    freopen("airport.in","w",stdout);
    int n=100000,m1=99999,m2=1,inf=1e8;
    printf("%d %d %d\n",n,m1,m2);
    for(int i=1;i<=m1;++i) printf("%d %d\n",i,inf-i);
    for(int i=1;i<=m2;++i) printf("%d %d\n",m1+1,inf-m1-1);
    return 0;
}
