PROGRAM EXPLANATION

Algorithm and explanation

  1. Initialize the sample values used to replace a word in text.
  2. Apply replace() and String to compute the required result.
  3. Display the result for replace a word in text and compare it with the documented sample output.

This example of replace a word in text computes the result directly from the prepared sample data. It demonstrates replace() and String and prints a deterministic result that can be checked against the sample output.

DEBUGGING CHECKLIST

Common mistakes

Check this

For replace a word in text, keep the data shape and value types consistent with replace().

Check this

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

Check this

Verify the final replace() 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.
