Code must be in C/C++ language using MPI

Suppose comm_sz = 8 and the vector x = (0,1,2,...,15) has been distributed among the processes using a block distribution. Implement an allgather operation using a butterfly structured communication(see diagram below) and point-to-point communication functions
