import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
public class Main {
public static void main(String[] args) throws IOException {
BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
int n = Integer.parseInt(in.readLine());
String[] input = in.readLine().split(" ");
int odd = 0, even = 0;
for (int i = 0; i < input.length; i++) {
int num = Integer.parseInt(input[i]);
if ((num & 1) == 1) odd++;
else even++;
}
System.out.printf("%d %d", odd, even);
}
}
