Please write program in C++ programming language.

Suppose the run-time of a serial program is given by Tserial = n, where the units of the run-time are in microseconds. Suppose that a paral- lelization of this program has run-time Tparallel =n-/p + log2 (p). Write a program that finds the speedups and efficiencies of this program for vari- ous values of n and p. Run your program with n= 10,20,40,...,320, and p=1,2,4,...,128. What happens to the speedups and efficiencies as p is increased and n is held fixed? What happens when p is fixed and n is increased
