Suppose an M × N array of doubles stored in a C row-major layout in the

sender system memory.

(a) Construct a continuous derived datatype MPI_newtype specifying a column of the array.

(b) Write an MPI_Send to send the first column of array. Try the same for

the second column. Note that the first stride starts now at array[0][1].
