PKU JudgeOnlineの1005番の問題

50ずつ削られる土地で、位置(x,y)がいつ削られるかという問題。

#include <iostream>
#define PI 3.141592
using namespace std;
int main(){
  int n,z;
  double x,y;
  cin >> n;
  for (int i=0; i<n; i++){
    cin >> x >> y;
    cout << "Property " << i+1 << ": This property will begin eroding in year " << (int)(PI*(x*x+y*y)/(2*50.0))+1 << ".\n";
  }
  cout << "END OF OUTPUT.\n";
}
