#include <iostream>

#include <algorithm>

using namespace std;

int main(){

int n;

cin>>n;

while(n){

int curmax=0, pos;

for(int i=1 ;i <=n; i++){

double temp,temp2;

cin>>temp>>temp2;

double k=max(min(min(temp,temp2),max(temp,temp2)/4), min(temp,temp2)/2);

if(curmax<k){

curmax=k;

pos=i;

}

}

cout<<pos<<endl;

cin>>n;

}

} 

用python同個邏輯會AC;

但這樣就暴斃，求解!
