Problem statement
Implement format_greeting(name, age) that returns a greeting sentence exactly in this format:
Hello, {name}! You are {age} years old.
The function should convert the age to text if necessary and insert the provided name and age into the template. Do not print; return the formatted string.
Task
Practice converting values to strings and using string formatting to produce a readable message.
Examples
Input format
Two arguments: name (string) and age (any value convertible to string).
Output format
A single string matching the greeting template exactly.
Constraints
Return a string. Preserve the input values as-is when converting (no rounding unless Python's default str() does it).
Samples
Sample 1
Input
format_greeting('Bob', '25')
Output
Hello, Bob! You are 25 years old.
Age provided as a string is placed into the template unchanged.
