Write a python script to do the following: 1. Generate 5 arrays (of length 1000) of random integers in [1, 5] with uniform distribution. 2. For each array X, compute the array S, where S[i], i = 0, 1, . . . , 999, is the average of the first i + 1 elements of X. 3. Plot all the 5 arrays S computed above in the same figure, and save the figure (see instructions below). 4. You may only use the following packages: numpy, matplotlib, os, sys, getopt 5. Note: Please make sure that your code does not crash. If it does, it will not be graded.
