method overloading: Parameter Count

Learning Objective: Understand method overloading with different parameter counts

In this problem, you will create a program that defines two overloaded greet methods with different parameter counts — a 1-parameter version (name only) and a 2-parameter version (name and age) — calls each appropriately, and displays the results to standard output.

Create two greeting method versions. Define both 1-parameter version (name only) and 2-parameter version (name + age).

Input

Line 1: Name 1 (string)
Line 2: Name 2 (string)
Line 3: Age (integer)

Output

Hello, [name1]!
Hello, [name2]! You are [age] years old.
