Answer:

def Average(num):

if num == 0:

return 0

val = 0

trueNum = num

for i in range(0, num):

try:

val += int(input("Enter value (%d out of %d): " % (i+1,num)))

except Exception as e:

print ("Error processing value. Non integer detected.")

try:

val += int(input("Enter value (%d out of %d): " % (i+1,num)))

except Exception as e:

print ("Error processing value. Non integer detected.")

print ("OMITTING value from average.")

trueNum -= 1

return val/trueNum

def main():

try:

num = int(input("Enter a value N for amount of items: "))

if num < 0:

raise(ValueError)

except ValueError:

print ("N must be positive integer.")

exit(1)

print("Average: ", Average(num))

exit(0)

if __name__ == "__main__":

main()

Explanation:

This program is written in Python to collect some integer value from the user as an upper bound of integers to be input for an average. Using this upper bound, the program checks to validate it is indeed an integer. If it not an integer, then the program alerts the user and terminates. If it is a user, the Average function is called to begin calculation. Inside the Average function, the user is prompted for an integer value repeatedly up until the upper bound. Using the sum of these values, the program calculates the average. If the user inputs a non integer value, the program will alert the user that the value must be an integer and ask again. If the user again inputs a non integer value, that iteration will be omitted from the final average. The program this prints the calculated average to the user.

Cheers.

Which of the following statements about interpreting colors are true? Select 3 options.

sukhopar [10]

Answer:

B, C and E

Explanation:

B :

White. In Western cultures, white symbolizes purity, elegance, peace, and cleanliness; brides traditionally wear white dresses at their weddings. But in China, Korea, and some other Asian countries, white represents death, mourning, and bad luck, and is traditionally worn at funerals.

Color psychology has a effect for the world's different cultures. Colors evoke various emotions and beliefs, as well as positive and negative connotations. A color may represent happiness and warmth in one culture but is associated with betrayal and jealousy in another.

Blue is one of the most commonly used colors in American marketing, often considered a safe color for a global audience, because it lacks significant negative connotations. Blue is tied to immortality, spirituality, and heaven in Eastern cultures.

Which sentences in the passage correctly describe a function?

quester [9]

Option D is correct.

Explanation :

In option A, it is not mandatory that a function will have arguments and it will return a value.
In option B, no formula begins with =.
In option C, it is not necessary to begin with /.
In option D, MAX function should return maximum value in the set given.

Thus, option D is correct because arguments of a function are always enclosed within parentheses

Example:

SUM (30,70)

A complete traversal of an n node binary tree is a(n)____ "operation if visiting a node is O(1)for the iterative implementation

ch4aika [34]

Answer:

B.O(n).

Explanation:

Since the time complexity of visiting a node is O(1) in iterative implementation.So the time complexity of visiting every single node in binary tree is O(n).We can use level order traversal of a binary tree using a queue.Which can visit every node in O(n) time.Level order traversal do it in a single loop without doing any extra traversal.
