Write a parallel program using MPI that computes the sum 1+2+...+p in the following manner: Each process i assigns the value i+1 to an integer, and then the processes perform a sum reduction of these values. Process 0 should print the result of the reduction. As a way of double checking the result, process 0 should also compute and print the value p(p+1)/2.
