In this part, you are asked to decipher the Assembly Language program in the attached mystery.s file. Specifically, you need to provide a concise description of what the program does and how it does it. You should also implement a Python program mystery that performs the same task in the same manner that the code in the attached file mystery.s does. The provided program takes a single integer as input. $ gcc -m32 -o mystery mystery.s $ /mystery 41 Value: 165580141 Hint: This program performs a wel known and easily recognizable computation. However, it includes an optimization to speedup the computation. You need to figure out both the basic functionality as well as the optimization, describe them, and replicate them in your Python code.
