of the n! possible inputs to a given comparison-based sorting algorithm, what is the absolute maximum number of inputs that could be correctly sorted with just n comparisons
Answers
The absolute maximum number of inputs that could be correctly sorted with just n comparisons is 2ⁿ, since that is the number of leaves in a decision tree of depth n.
The absolute maximum number of inputs can be found using the concept of decision trees. A decision tree represents all possible outcomes of a comparison-based sorting algorithm for a given input of size n.
Each node of the tree represents a comparison between two elements, and each edge represents the outcome of that comparison (i.e., whether the two elements were swapped or not). The leaves of the tree represent the possible sorted outputs for the given input.
Since there are n! possible inputs of size n, there are n! possible leaves in the decision tree. In order for the sorting algorithm to correctly sort all possible inputs, each leaf of the decision tree must represent a unique output. Therefore, the decision tree must have at least n! leaves.
Now, let's consider the depth of the decision tree. Each comparison reduces the number of possible outputs by a factor of 2 (i.e., there are two possible outcomes of a comparison: either the elements are swapped or they are not). Therefore, in order to get n! leaves, the decision tree must have a depth of at least log2(n!) comparisons.
Using Stirling's approximation, we can approximate n! as:
n^(n+1/2) * e^(-n) * sqrt(2pi).
Therefore, log2(n!) is approximately:
(n+1/2) * log2(n) - n * log2(e) + 1/2 * log2(2pi).
Dropping the constants and lower-order terms, we can approximate log2(n!) as n * log2(n).
Therefore, the absolute maximum number of inputs that could be correctly sorted with just n comparisons is 2ⁿ, since that is the number of leaves in a decision tree of depth n. However, it is important to note that this bound is not achievable by any comparison-based sorting algorithm, since all such algorithms have a worst-case time complexity of O(n log n).

Write the removeevens() function, which receives a vector of integers as a parameter and returns a new vector of integers containing only the odd numbers from the original vector. the main program outputs values of the returned vector. hint: if the original vector has even numbers, then the new vector will be smaller in length than the original vector and should have no blank element. ex: if the vector passed to the removeevens() function is [1, 2, 3, 4, 5, 6, 7, 8, 9], then the function returns and the program output is: [1, 3, 5, 7, 9] ex: if the vector passed to the removeevens() function is [1, 9, 3], then the function returns and the program output is: [1, 9, 3]
main.py 1 def remove evens(nums): 2 # Type your code here. 3 4 if __name__ ==' ___main___':
5 nums = [1, 2, 3, 4, 5, 6, 7, 8, 9] 6 result = remove_evens(nums) 7 8 print(result)
Answers
Answer:
def remove_evens(nums):
# Create an empty list to hold the odd numbers
odds = []
# Loop through the input list and check if each number is odd
for num in nums:
if num % 2 != 0:
odds.append(num)
# Return the list of odd numbers
return odds
if __name__ == '__main__':
nums = [1, 2, 3, 4, 5, 6, 7, 8, 9]
result = remove_evens(nums)
print(result)
Explanation:
In this implementation, we first create an empty list called odds to hold the odd numbers. We then loop through the input list nums, checking if each number is odd using the modulus operator (%). If the number is odd, we append it to the odds list.
Finally, we return the odds list, which contains only the odd numbers from the input list. In the main program, we pass the input list [1, 2, 3, 4, 5, 6, 7, 8, 9] to the remove_evens() function, and print the resulting list [1, 3, 5, 7, 9].

T/F : the hard drives of devices to be disposed of should be destroyed before they are sold or recycled. _________________________
Answers
Answer: True
Explanation: If someone gets their hand's on the drive it can access personal data. Often this only happens in external hard drives however, it is better safe than sorry.
The hard drives of devices to be disposed of should be destroyed before they are sold or recycled. The reason behind this is that the hard drives contain sensitive information such as personal data, confidential business information, financial data, and more. If these hard drives end up in the wrong hands.
Simply deleting files or formatting the hard drive is not enough as the data can still be recovered using data recovery software. Therefore, the hard drives should be physically destroyed, making the data irretrievable. This can be done through methods such as degaussing, shredding, or melting. Many businesses and organizations have strict data protection policies that require the secure destruction of hard drives before disposal. Failure to follow these policies can result in data breaches, legal repercussions, and damage to the organization's reputation.
In conclusion, the hard drives of devices to be disposed of should be destroyed before they are sold or recycled to protect sensitive information from falling into the wrong hands. The explanation behind the need to destroy hard drives before disposal is to protect the sensitive information stored on them. Hard drives contain a vast amount of data that can include personal information, financial details, and confidential business data. If this information is accessed by unauthorized individuals, it can lead to identity theft, financial loss, and reputational damage. Deleting files or formatting the hard drive may give a false sense of security as the data can still be recovered using data recovery software. Physical destruction of the hard drive is the only way to ensure that the data is irretrievable. Methods such as degaussing, shredding, or melting are commonly used for this purpose. Businesses and organizations have data protection policies in place to ensure that sensitive data is securely disposed of before devices are sold or recycled. Failure to comply with these policies can result in legal and financial consequences, as well as damage to the organization's reputation. Overall, the need to destroy hard drives before disposal is essential for data protection and privacy. By following best practices and secure disposal methods, individuals and organizations can ensure that their sensitive information remains safe and secure.

Which of the following decisions involve a choice between
internal and external production?
Repurchase order
Keep-or-drop
Sell-or-process-further
Special-order
Make-or-buy
Answers
One of the decisions that involve a choice between internal and external production is make-or-buy.
This decision refers to whether a company should manufacture a particular product or service in-house or outsource it to a third-party supplier. An organization can make-or-buy anything from raw materials to finished products, services, and software, depending on its strategic objectives, capabilities, and cost considerations.
In most instances, the decision to make-or-buy involves a trade-off between the costs and benefits of internal and external production. A company should consider various factors before making the decision, such as the availability of production capacity, the level of expertise required, the cost of production, the quality standards, the lead time, and the risk involved.
For instance, if a company has enough production capacity, technical expertise, and raw materials, it may prefer to make the product in-house. This decision can help the company maintain better control over the quality, timing, and cost of production. Moreover, it can leverage its core competencies and knowledge to create unique value for customers.
On the other hand, if a company lacks the production capacity, expertise, or raw materials, or if it faces a shortage of time or money, it may prefer to buy the product or service from an external supplier. This decision can help the company reduce its production costs, avoid capital investments, and focus on its core competencies.
In conclusion, make-or-buy is one of the critical decisions that companies face in managing their production activities. The decision requires a thorough analysis of the benefits and drawbacks of internal and external production and a consideration of various factors that influence the decision. Therefore, companies must make informed decisions that align with their strategic goals, market demands, and financial objectives.
