PROGRAM EXPLANATION
Algorithm and explanation
- Initialize the sample values used to find factorial with a loop.
- Process the data step by step using for and Factorial.
- Display the result for find factorial with a loop and compare it with the documented sample output.
This example of find factorial with a loop processes the sample values in a controlled iteration. It demonstrates for and Factorial and prints a deterministic result that can be checked against the sample output.

DEBUGGING CHECKLIST
Common mistakes
Check this
For find factorial with a loop, keep the data shape and value types consistent with for.
Check this
Keep every dependent statement inside the correct indented Python block.
Check this
Verify the final for and Factorial result against the sample before trying new data.
Try it yourself
Practice: Run the program with the sample input, predict its output, and then test one boundary case of your own.
