import java.util.*;public class Main {   	public static void main(String[] args) {   		Scanner sc=new Scanner(System.in);		while(sc.hasNext()) {   			int first=sc.nextInt();//排头,表示数字的个数			if(first==0) break;//如果n=0,则表示输入结束			int positiveNumber=0;//正数个数			int negativeNumber=0;//负数个数			int zeroNumber=0;//零的个数			double[] arr=new double[first];			for(int i=0;i
0) { //是正数 positiveNumber++; }else if(arr[i]<0) { //是负数 negativeNumber++; } else { //是零 zeroNumber++; } } System.out.println(negativeNumber+" "+zeroNumber+" "+positiveNumber); } }}
