Recursive Method Output

Consider the following class definition.

public class Main {
    public static void printPattern(int n) {
        if(n < 1)
            return;
        printPattern(n - 1);
        System.out.print(n + " ");
    }
    public static void main(String[] args) {
        printPattern(4);
    }
}

What is printed as a result of executing the main method?
