use Advanced C++ techniques, containers and features to refactor the C/C++ algorithm. The purpose is to
replace appropriate declarations and code segments with Advanced C++ declarations and code.

* Replace all arrays with appropriate STL containers.

* Use STL algorithms to REPLACE existing logic where appropriate.

* Use smart and move pointers where pointers are needed.

* Use lambda expressions where appropriate.

* Use C++ style casting when needed.

* Look for opportunities where tuples could be used.

* The code listing is in C and C++.

If there are logic or syntax problems, please fix.
