PROGRAM EXPLANATION
Algorithm and explanation
- Initialize the sample values used to find factorial recursively.
- Apply Recursion and Base case to compute the required result.
- Display the result for find factorial recursively and compare it with the documented sample output.
This example of find factorial recursively computes the result directly from the prepared sample data. It demonstrates Recursion and Base case and prints a deterministic result that can be checked against the sample output.

DEBUGGING CHECKLIST
Common mistakes
For find factorial recursively, keep the data shape and value types consistent with Recursion.
Keep every dependent statement inside the correct indented Python block.
Verify the final Recursion and Base case result against the sample before trying new data.
