Easy Polymorphism & Function Overloading

Problem Statement

Create a `Calculator` class. Overload an `add` method so that it can accept either two integers or three integers, returning their sum. Read three integers. First print the sum of the first two integers, then print the sum of all three.

Input Format

Three space-separated integers.

Output Format

Print 'Sum of 2: [val]' followed by 'Sum of 3: [val]'.

Constraints

None

Sample Input

5 10 15

Sample Output

Sum of 2: 15
Sum of 3: 30

Explanation

Methods can be cleanly overloaded based strictly on the number (arity) of arguments passed into them.

Starter Code

#include <iostream>

class Calculator {
public:
    // Write your overloaded add methods here
};

int main() {
    // Read input and test overloads
    return 0;
}
