Suppose comm sz = 8 and n = 16.
a. Draw a diagram that shows how MPI Scatter can be implemented using tree-structured communication with comm sz processes when process 0 needs to distribute an array containing n elements.
b. Draw a diagram that shows how MPI Gather can be implemented using tree-structured communication when an n-element array that has been distributed among comm sz processes needs to be gathered onto process 0
