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

DEBUGGING CHECKLIST
Common mistakes
Check this
For reverse a string, keep the data shape and value types consistent with Slicing.
Check this
Apply Slicing in the same order shown by the algorithm; changing the order can change the result.
Check this
Verify the final Slicing and String 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.
