Write a Python program that reads from each line of an input file called grades.txt, a student id followed by the student grades in 3 exams. The program will then calculate the average of the student and save in a file called results.txt the student id followed by the calculated average. For example, if the grades.txt contains si11 60 60 90 S222 89.5 90 89 S333 42 50 43 The file results.txt will contain si11: 70.00 S222: 89.50 S333: 45.00

Prove each statement using a proof by exhaustion.
Given an integer say 45, to find the sum of 45 with 8 in binary form (see the figure below), we can use the TM designed in slides 79-90 of the notes "Turing Machines and Equivalent Models I" twice to find the result. A more effective way is to design a TM to do the addition with 8 directly. 1000 101101 A + = ? Such a TM can be designed by extending the TM designed in slides 79-90 of the notes "Turing Machines and Equivalent Models I". The TM has 14 instructions and 6 states: 0, 1, 2, 3, 4, and halt. Six instructions of such a TM have been given in the first and the second tables below. Fill out the remaining blanks in the first and the second tables and also blanks in the third table to show the remaining instructions of the TM (you have to use your own text boxes here)
