PROGRAM EXPLANATION

Algorithm and explanation

Initialize the sample values used to split and join words.
Apply split() and join() to compute the required result.
Display the result for split and join words and compare it with the documented sample output.

This example of split and join words computes the result directly from the prepared sample data. It demonstrates split() and join() and prints a deterministic result that can be checked against the sample output.

DEBUGGING CHECKLIST

Common mistakes

Check this

For split and join words, keep the data shape and value types consistent with split().

Check this

Apply split() in the same order shown by the algorithm; changing the order can change the result.

Check this

Verify the final split() and join() 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.
