PROGRAM EXPLANATION
Algorithm and explanation
- Initialize the sample values used to create and access a list.
- Apply List and Indexing to compute the required result.
- Display the result for create and access a list and compare it with the documented sample output.
This example of create and access a list computes the result directly from the prepared sample data. It demonstrates List and Indexing and prints a deterministic result that can be checked against the sample output.

DEBUGGING CHECKLIST
Common mistakes
Check this
For create and access a list, keep the data shape and value types consistent with List.
Check this
Apply List in the same order shown by the algorithm; changing the order can change the result.
Check this
Verify the final List and Indexing 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.
