public class Calculator {
    static int add(int a, int b) {
        return a + b;
    }

    static int add(int a, int b, int c) {
        return a + b + c;
    }
    
    public static void main(String[] args) {
        System.out.println(add(1, 2));
        System.out.println(add(1, 2, 3));
    }
}

What will be the output of the above program?
