String Interpolation

String Interpolation

F#'s $"..." strings let you embed any expression with {expr}:

let name = "Alice"
let age = 30
printfn $"Hello, {name}! You are {age} years old."
// Hello, Alice! You are 30 years old.

You can embed arbitrary expressions:

let a = 3
let b = 4
printfn $"{a} + {b} = {a + b}"
// 3 + 4 = 7

Your Task

Write a function greet that takes a name and age and returns the string "Hello, <name>! You are <age> years old." using string interpolation.
