In this problem you will write a function that takes in a single integer (positive, negative, or zero) and produces an array of all of its individual digits along with a boolean which flags if the number is negative (often called the sign bit). the list of digits should begin with the lowest place and increase to the highest place. main function:

input variables: • a scalar representing the integer to be studied
output variables: • a vector of each digit in the order from lowest place to highest place

• a scalar boolean which is 1 if the number is negative and 0 otherwise a possible sample case is: » [digits, sign] = lxx_qyy(1234) digits = 4 3 2 1 sign = 0 » [digits, sign] = lxx_qyy(-9) digits = sign %3d

The solution code is written in Python 3.

def LXX_QYY(num): num_list = [] if(num > 0): num_str = str(num) lastIndex = len(num_str) - 1 for i in range(0, len(num_str)): num_list.append(int(num_str[lastIndex - i])) return([0, num_list]) else: num = - (num) num_str = str(num) lastIndex = len(num_str) - 1 for i in range(0, len(num_str)): num_list.append(int(num_str[lastIndex - i])) return ([1, num_list]) [digits, sign] = LXX_QYY(1234) print(digits) print(sign) [digits, sign] = LXX_QYY(-5678) print(digits) print(sign)

Explanation:

Firstly, let's create a function LXX_QYY() that take one input number, num. (Line 1 - 20)

Since one of the output is a vector of digit, we create a new list, num_list to hold the vector of digit.

Prior to generating the vector of digit, we need to handle two possible types of number, which are positive and negative. Define an if-else statement (Line 3 & 11). If the number is positive, program will go through Line 4 -10, else Line 12 - 20. One different between this two parts of codes is that, if the number is negative, it is necessary to multiply the number with -1 to convert it to positive.

To capture the individual digit of the input number, we need to convert the number into string (Line 4) so that we can traverse through each of the digit using for loop (Line 7).

Besides, we also need to ensure the digit captured in order from lowest place to highest place. Therefore, we need to extract the digit one after another from the last index (Line 5) and then add it into the num_list (Line 8).

Next, we can return the num_list along with the sign 0 (if the number is positive) or 1 (if the number is negative) as a list.

At last, we can test the function with two sample cases (Line 22 & 26) and they shall give the output as:

[4, 3, 2, 1]

[8, 7, 6, 5]

Write a defining table and then a program that determines if you can sleep in or not. your program should get all its input from your computer’s clock. on all weekdays (monday through friday) that are not holidays, your program should output “get up! ” on all other days (weekends and holidays), your program should output “sleep in.” the three holidays that your program must check for are january 1 (new year’s day), july 4 (u. s. independence day), and december 25 (christmas). you don’t need to include other holidays in your program because most other holidays do not occur on a fixed day each year.

Explain the circumstances for which the interquartile range is the preferred measure of dispersion. what is an advantage that the standard deviation has over the interquartile range? choose the correct answer below. a. the interquartile range is preferred when the distribution is symmetric. an advantage of the standard deviation is that it increases as the dispersion of the data increases. b. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation. c. the interquartile range is preferred when the distribution is symmetric. an advantage of the standard deviation is that it is resistant to extreme values. d. the interquartile range is preferred when the data are bell shaped. an advantage of the standard deviation is that it is resistant to extreme values. e. the interquartile range is preferred when the data are skewed or have outliers. an advantage of the standard deviation is that it uses all the observations in its computation. f. the interquartile range is preferred when the data are bell shaped. an advantage of the standard deviation is that it increases as the dispersion of the data increases.
