My first instinct was recursion and that's basically the answer, but I fumbled a bit explaining the base case clearly.
Clarify the constraints (e.g., recursion allowed, language features) and then present a recursive solution that prints numbers from 1 to n. Discuss trade-offs like stack depth and potential optimizations like tail recursion or using functional constructs.
Pro tip: Mention that recursion uses the call stack as an implicit loop, and for large n, consider alternatives like using a generator or built-in functions to avoid stack overflow. This shows awareness of practical limits.
Ask if recursion is allowed, if the function should be pure or have side effects, and if there are constraints on n (e.g., large values).
Design a function that prints numbers from 1 to n by recursively calling itself with n-1 and then printing n (or vice versa).
Define the base case when n <= 0 to stop recursion and avoid infinite calls.
Mention stack overflow risk for large n, and suggest tail recursion optimization or using language-specific features like generators or built-in functions.
Write clean code in the preferred language, and walk through an example (e.g., n=3) to demonstrate correctness.
