Degger [83]3 years ago

Answer:

def rec_dig_sum( num ):

   num_list = [ digit for digit in str(num)]

   total = 0

   for x in num_list:

       total += x

   return total

def dict_of_rec_dig_sums(low, high):

   mydict = dict()

   for number in the range(low, high+1):

      mydict[rec_dig_sum(number)] = number

   return mydict

Explanation:

The python program defines two functions, "rec_dig_sum" and "dict_of_rec_dig_sums". The former accepts a number and returns the sum of the digits of the number while the latter accepts a low and high number range.

The program returns a dictionary with the recursive sum as the keys and the number count as the values.

The input nums is supposed to be an array of unique integers ranging from 1 to nums.length (inclusive). However, there is a mist
Elden [556K]

The program is an illustration of loops.

Loops are used to perform repetitive and iterative operations.

The program in Python where comments are used to explain each line is as follows:

#This intializes the list

nums = [5,4,4,2,1]

#This gets the length of the list

size = len(nums)

#This iterates through the list

for i in range(size):

   #The following if condition determines the repeating number

   if nums[abs(nums[i])-1] > 0:

       nums[abs(nums[i])-1] = -nums[abs(nums[i])-1]

   else:

       repeating = abs(nums[i])

   #The following if condition determines the missing number

   if nums[i]>0:

       missing = i + 1

   

#This calculates and prints the sum of the missing and the repeating numbers

print(repeating+missing)

What CSS property do you use to determine whether flex items are displayed horizontally or vertically
Hoochie [10]

Answer:

Flex direction

Explanation:

HTML is an acronym for hypertext markup language and it is a standard programming language which is used for designing, developing and creating web pages.

Generally, all HTML documents are divided into two (2) main parts; body and head.

The head (header) contains information such as version of HTML, title of a page, metadata, link to custom favicons and cascaded style sheet (CSS) etc.

On the other hand, the body of a HTML document contains the contents or informations that a web page displays.

Generally, the part of a HTML document where the cascaded style sheet (CSS) file is linked is the header.

A style sheet can be linked to an HTML document by three (3) main methods and these are;

I. External style.

II. Inline style.

III. Embedded (internal) style.

Flex direction is a CSS property that's used to determine whether flex items are displayed horizontally or vertically.

Can you help me with these AP Computer Science Questions. (THIS IS DUE BY 1:30 PM today) you have to evaluate the Boolean Expres
vfiekz [6]

Answer + Explanation:

'and' -> both statements are 'True' to evaluate as 'True'.

'or' -> at least one statement is 'True' to evaluate as 'True'.

1. True (grade has the value of 82, so the statement evaluates to 'True').

2. True (Both statements are true, this expression evaluates to 'True').

3. False (Both statements are false, this expression evaluates to 'False').

4. True (the != operator means <em>not equal.</em> Since the 'name' variable holds the string 'Rumpelstiltskin', name != 'Rumpelstiltskin' evaluates to 'False'. The 'not' operator returns the opposite of the given Boolean expression, so this expression evaluates to 'True').

5. True (name == 'Rumpelstiltskin' evaluates to 'True', so this expression is true).

6. False (All statements evaluate to 'False').

7. True (All statements evaluate to 'True').

8. False (All statements evaluate to 'True' except for <em>not(x == - 3) </em>which evaluates to 'False', so the whole statement now becomes false).

9. True (<em>grade+5 < 90 and grade >= 80 </em>evaluates to 'True', so this whole expression becomes true).

10. True (<em>grade > 0 and x % 2 == 1 </em>evaluates to 'True')

Hope this helps :)
