Note: The code must be written in c++

Exercise: Send RecyCollectives / GatherScatter QUESTION: Write an MPI program that computes the average across all numbers in an array. 1. Generate a random array of numbers on the root process (process 0). 2. Scatter the numbers to all processes, giving each process an equal amount of numbers. 3. Each process computes the average of their subset of the numbers. 4. Gather all averages to the root process. The root process then computes the average of these numbers to get the final average
