Exercise 1 - Turing Machines Submit Assignment
PURPOSE
This exercise is designed to free your mind from thinking of big picture problems, and instead to focus on details. This mindset will be crucial when we study assembly language. Think Lego blocks. Focus on one block at a time, rather than the elephant you are trying to build.
TASK
Take the problem of determining whether a number is a prime number. Draw a flowchart to represent this algorithm. Keep each box in the flowchart as simple as possible, with only one operation in each box. Each box will represent a Turing machine. Use rectangles to represent arithmetic operations such as addition, subtraction, multiplication, division and modulus (remainder). Use diamonds to represent relational operations such as equals, not equals, less-than, etc. Use circles to represent the different outcomes: one for prime and one for not prime.
OPTIONS
You may use any tool you wish. I recommend LucidChart, a free online program at lucidchart. com. Many word processors, such as MS Word, have drawing tools. You may also use a drawing program like MS Paint. You may even draw your chart by hand and submit a picture.

Your task this week is to write a very simple spam classifier in python. it will classify messages as either spam (unwanted) or ham (wanted). the program will have a set of spam_words, words that are known to appear in spam messages. that set is included in the template file spam.pypreview the document. you will also define a spam threshold which reflects the allowed percentage of spam words in the message. you'll compute a 'spam indicator', which is the ratio of spam words to the total number of unique words in the message. if the spam indicator exceeds the spam threshold, the message is classified as spam. otherwise it is classified as ham. we'll assume that the spam threshold is a constant and has a value of 0.10. your program will prompt the user for a message and then will print the corresponding spam indicator with two decimal digits and the corresponding classification (spam or ham). the program will be case insensitive. the spam words are detected whether they are in lower case or upper case or mixed case. each word, spam or not, is counted once (even if it appears multiple times in the message.) the program will remove punctuation from the message before identifying the words and computing the spam indicator. for example '! ' must be identified as the spam word 'now'.

Font size, font style, and are all aspects of character formatting.
