import java.util.Scanner;

public class CalcNumbersType
{
    public static void main(String args[])
    {
    	// intialize and declaring the objects.
        int n,positive=0, negative=0, zero=0, i;
        int arr[] = new int[50];
        Scanner scan = new Scanner(System.in);
       
        // enter number you have to enter.
        System.out.print("How many Number you want to Enter : ");
        n = scan.nextInt();
		
        // enter the numbers.
        System.out.println("Enter " +n+ " Numbers : ");
      
        // this is to calculate the type of the number.
        for(i=0; i<n; i++)
        {
            arr[i] = scan.nextInt();
        }
        for(i=0; i<n; i++)
        {
            if(arr[i] < 0)
            {
                negative++;
            }
            else if(arr[i] == 0)
            {
                zero++;
            }
            else
            {
                positive++;
