An Alien group was visiting Earth to build an interstellar friendly relationship. Unfortunately, a lightening hit their space ship and corrupted their data storage (Yeah right, super intelligent beings that can fly across the galaxy have no surge protectors.)   They were able to salvage a file. random_number.txt (The file can be downloaded directly from the File Folder as well)    These Aliens do not have the concept of “Binary Numbers”. They have developed their math and science by using Trinary Numbers – 0, 0.5, and 1. Here is what you need to do. 1. Read the file 2. Plot the value 3. Reconstruct the original data.        a.  if a number = 0.33 and number 0.67, convert to 1.  4.  Plot 3 data set –            a) corrupted data (let’s call this x1),            b) reconstructed data (let’s call this x2) , and            c) the absolute value of the difference between x1 and x2     in a single figure.   5. Do not forget to label!
