Writing methods that take multi-dimensional arrays as parameters and/or return multi-dimensional arrays is similar to working with single-dimensional arrays. The syntax for a method that accepts a two-dimensional array as a parameter is as follows: returnType methodName( arrayType[][] arrayParameterName ) The syntax for a method that returns a two-dimensional array is the following: returnArrayType [][] methodName( arrayType [ ][ ] arrayParameterName ) In this Lab, you will work with a 4-row, 20-column, two-dimensional array of integers. You will write methods that perform the following operations: 1. Fill the 2-D array with random numbers between 50 and 80. 2. Print the array. 3. Set every array element of a given row to a specified value. The value is a parameter of a method. 4. Find the minimum value in a given column of the array. The column is a parameter of a method.

What tool can discover and report computer errors and conflicts that occur when you first turn on a computer and before the operating system?

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'.

The total revenues for a company are $150,223 and the total expenses were 125,766. if you are calculating the net income, which of these spreadsheets would you use? insert a spreadsheet with $150,223 in cell b2 and 125, 766 in cell b3. enter a formula =b2-b3. the formula should be showing in the formula bar. insert a spreadsheet with $150,223 in cell b2 and 125, 766 in cell b3. enter a formula =b2+b3. the formula should be showing in the formula bar. insert a spreadsheet with $150,223 in cell b2 and 125, 766 in cell b3. enter a formula =b2/b3. the formula should be showing in the formula bar. insert a spreadsheet with $150,223 in cell b2 and 125, 766 in cell b3. enter a formula =b2*b3. the formula should be showing in the formula bar.
