// inplace_mergeP.cpp
// compile with: /EHsc
// Illustrates how to use the predicate version of
// the inplace_merge function.
//
// Functions:
//    inplace_merge - Merge two sorted sub-sequences in place into a
//                    single sorted list using the compare function.
//
//    begin - Returns an iterator that points to the first element in a
//            sequence.

//    end - Returns an iterator that points one past the end of a sequence.
