For this assignment, you will be creating an interactive Tic-Tac-Toe game. Turn this into a Java Program. So let’s get started!Part 1: Your Tic-Tac-Toe game!You love playing tic-tac-toe, but don’t always have someone to play the game with. So, you decide to create your own that you can play against the computer. This will be a standard tic-tac-toe game with X’s and O’s where the players alternate taking turns placing their tokens (i. e., X or O, depending on which one they are). It will include:· Standard 3 x 3 playing board (hint: use 2D arrays)· A winning game is either:o 3 acrosso 3 up and downo 3 diagonally· Tie games are possible if a winning game is not achieved.· The game board with associated placement of the played X’s and O’s must be displayed after each turn.

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'.

3. bob is arguing that if you use output feedback (ofb) mode twice in a row to encrypt a long message, m, using the same key each time, it will be more secure. explain why bob is wrong, no matter what encryption algorithm he is using for block encryption (15 points).

Some of the first computer games were created in the early 1970s by college students experimenting after hours to see what the were capable of doing.
