Problem 01 • Step 01
Evaluate a Number
This is the simplest kind of expression: just a number.
When the evaluator sees a number like 5, that’s already the final result. There’s nothing else to break down or compute. This is called the base case — the point where no further evaluation is needed.
Your task is to tell the evaluator what will be the result of evaluation when the input is a plain number.
