Actually first question is how to write this in C++ I can't understand the question to write the solution :(
(Replacement Selection)
Program input:
 An unordered file containing N sortable data (such as int, double, string etc.)
 B memory zones that can hold data, representing the buffer pool
Program Output:
 N / 2D RUN files, each containing "Approximately" 2B pieces of data
The program should end correctly with different N and B values. In the buffer zone, you need to implement a HEAP scaffolding as in Presentation: 14 in the EXT-SORT presentation.
