Argument Cannot Be Null

Read an id. If id is 1 the name is Alice, otherwise the name is null. If the name is null, throw new ArgumentNullException(nameof(name), "name not found"). Otherwise print Name: <name>. Catch the ArgumentNullException and print exactly Error: name not found. Use top-level statements with try/catch.

Input 1 prints: Name: Alice
Input 2 prints: Error: name not found

Expected Output:

Name: Alice↵

= newline. The output ends with a newline — print one after the last line.
