Three batch jobs, A through C, arrive at a high performance computer at the same time. They have estimated running times of 10, 6 and 2 minutes respectively. At time 3, jobs D and E arrive, which take 4 and 8 minutes respectively. For each of the following scheduling algorithms, determine the mean turnaround time. Ignore any process switching overhead.
a. First come, first serve
b. Shortest job first
c. Priority scheduling
For (a), assume that the system is multiprogrammed, and that each job gets its fair share of the CPU. For (b) and (c) assume that only one job runs at a time, until it finishes. All jobs are completely CPU bound.

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'.

Program description: a c# app is to be created to produce morse code. the morse code assigns a series of dots and dashes to each letter of the alphabet, each digit, and a few special characters (such as period, comma, colon, and semicolon). in sound-oriented systems, the dot represents a short sound and the dash represents a long sound. separation between words is indicated by a space, or, quite simply, the absence of a dot or dash. in a sound-oriented system, a space is indicated by a short period of time during which no sound is transmitted. the international version of the morse code is stored in the data file morse.txt.
