SEARCH_SERIAL
Search for Integer so that F(J) = C

SEARCH_SERIAL is a C++ program which searches integers between A and B for a value J such that F(J) = C.

For the particular example considered here, the solution will be F(1,674,924,981) = 45.

This program is intended as a starting point; both MPI and OpenMP can be used to make a parallel version.
