ASSIGNMENT 1 Write a parallel C program that returns the answer for the following problem: Given a nonempty set S, with elements {a1, a2, a3, ...}, and a integer N, find the number of nonempty subsets of S, such that the sum of all elements in this subset equals to N. This problem is NP-complete, meaning that currently there is no way to sovle it efficiently. However, since this assignment is targeted for parallel computing, the algorithm is not an important part. You only need to take the simplest approach: enumerate all the subset of S, add up the elements and compare to N, count one if there is a match, and finally return the total number of counts. ASSIGNMENT 2 Write a parallel C program that reads an image from a binary BMP file on disk, inverts all of the pixels, and saves the image as a new BMP file
