// Exercise 1: Where, Select, OrderBy (easy)
//
// Implement GetAdultNamesSorted so that, given a list of (Name, Age) people,
// it returns the names (uppercased) of everyone 18 or older, sorted
// alphabetically ascending. Use method-syntax LINQ (Where/Select/OrderBy) —
// no manual loops.
//
// Run with: dotnet run (inside a console project) or paste into a Main method.
