Need to write for below 48 test cases

 Notes on Text-Replace :

1. Time spent on the evaluation
2. A list of the testing performed
3. The list of problems discovered and suggestions for how they may be corrected
4. Any additional documentation or explanations of work.  It's especially helpful if you explicitly call out any known gaps in your testing.  If you leverage third party work that's fine - just document this so we don't mistake that work for your own.

Notes on Concordance test:

Attached file contains a problem for you to solve.

When you are done, please submit:

1) If you write any code, send the source code and instructions for building and running the solution.  Zip files or text files are fine - don't send executable.

2) The amount of time you spent solving the problem.
