The worst-case running time of the operations on this data structure would be O(n), where n is the number of elements in the linked list. The worst-case amortized running time of the operations on this data structure would still be O(n), since the worst case is still possible.

The maximum time that can be used to execute a lookup operation in a linked list is proportional to the size of the list. Each element of the list will be checked one by one, which means that it will take a long time to execute when there are many elements. The lookup operation will be executed in O(n) time on the worst-case because of the list of size n.

The worst-case amortized running time is O(1) because it considers the total time taken to execute all insert and lookup operations. This is why the cost of a particular operation is distributed among all other operations that are executed on the data structure.

When multiple insert operations are executed, the client will insert elements at the beginning of the linked list. Since the elements are unique and there is only one lookup operation, the cost of the lookup operation is shared among all the insert operations, resulting in O(1) amortized time.

Answer:

question = "What is the largest planet in our solar system?"

answer = "Jupiter"

user_input = input(question)

if user_input.lower() == answer.lower():

print("That's correct!")

else:

print("Sorry, that's incorrect. The correct answer is", answer)

Explanation:

In this code, we first define the question and answer as variables. Then we use the input() function to prompt the user to enter an answer to the question. We convert the user's input to lowercase using the lower() method to make the comparison case-insensitive.

We then use an if statement to check if the user's input matches the correct answer. If it does, we print a message indicating that the user is correct. If the user's input does not match the correct answer, we print a message indicating that the user is incorrect and we provide the correct answer.

Answer:

while True:

num = int(input())

if num <= 0:

break

if num % 2 == 0:

print(num)

Explanation:

The while loop runs indefinitely until it encounters a non-positive integer input. Within the loop, we read the integer input using input() and convert it to an integer using int(). We then check if the integer is positive or not. If it is not positive, we break out of the loop. If it is positive, we check if it is even by checking if the remainder after dividing by 2 is 0. If it is even, we print it out using print().

Nordstrom has been struggling with declining profits, and while its e-commerce business is growing, it is not as profitable as its physical stores .

The company's shares have fallen 30% in the past year, and after its fourth-quarter earnings missed analyst estimates, Nordstrom admitted that it needed to improve its e-commerce operations . Despite growing digital sales, rising costs are crimping Nordstrom's profits, and the company is transitioning to a digital-first business to try to address the issue.

Therefore, it appears that the primary reason for Nordstrom's declining profits is not solely related to e-commerce, but rather a combination of factors such as rising costs, declining physical store sales, and a need to improve its e-commerce operations.

Explanation:

The mechanical advantage of a lever of a grain crusher is the ratio of the output force to the input force. It is a measure of how much easier it is to do a job using the lever compared to doing it without. For example, if the output force is twice as great as the input force, then the mechanical advantage of the lever would be 2. This means that the job can be done with half the effort. The mechanical advantage of a lever of a grain crusher can be increased by increasing the length of the lever arm, which reduces the input force required to move the grain. This makes it easier to crush the grain, as less force is needed to do the job.

(a) The code initializes two variables, x and y, to the values of 10 and 20, respectively. It then declares a function, f, which takes two arguments, a and b, and returns the result of a + b. The code then calls the function with the values of x and y as arguments, and assigns the result to the variable z. Finally, the code prints the value of z, which is 30.

(b) The variables x, y, and z will be stored in the static memory area, as they are global variables. The variables a and b will be stored in the stack area, as they are local variables within the function f. There are no variables stored in the heap area in this program.

When line 30 is executed, the function f will be called with the values of x and y as arguments. The function will then return the result of a + b, which is 30, and this value will be assigned to the variable z. The diagram below shows the functions in the memory at this point:

The given query asks for a recursive function that finds the largest substring in a given string that starts and ends with a specified non-empty substring. One suggested approach is to find the first and last occurrences of the substring, and then calculate the length of the resulting substring.

If the difference between the two indexes is zero or negative, the function should be called again with a shortened string. This can be repeated until a valid result is found . Another solution is to recursively call the function with the substring removed from the beginning and end of the string until the substring is no longer present. The length of the resulting string is then returned .In computer language, a string is a sequence of characters that is used to represent text or other data. A string can include letters, numbers, symbols, and whitespace, and it can have any length.

A substring is a smaller sequence of characters that is contained within a larger string. A substring can be any length, but it must be a contiguous sequence of characters that occurs within the larger string.

In programming, there are many tasks that involve manipulating strings and substrings. For example, you might need to search for a particular substring within a larger string, extract a specific substring from a larger string, or replace one substring with another.

There are many built-in functions and libraries in programming languages that provide tools for working with strings and substrings, such as the substring method in JavaScript, the string module in Python, or the String class in Java.

The best way that Safiya can improve the ability of the machine learning algorithm to detect all pedestrians is by adding videos of people using wheelchairs and strollers into the training data set. Option A is correct.

By adding more examples of people using wheelchairs and strollers to the training data, the machine learning algorithm can learn to recognize the unique features and movement patterns of these individuals and improve its ability to detect them.

Crowd-sourcing the data can be a good approach if the required videos are not readily available. Adding rules to the network can be helpful, but it may not be sufficient in detecting all types of pedestrians and can lead to overfitting.

Therefore, adding more diverse training data is generally a better approach for improving the performance of the algorithm. The correct answer is A.

Safiya is a software engineer at a company that's developing software for self-driving cars. she's working on software that uses computer vision and machine learning algorithms to detect pedestrians walking near the car and trigger the brakes when needed. after training the algorithm on a large dataset of training data (videos of pedestrians walking near cars), they try it out in cars with backup drivers. the drivers report that it detected most pedestrians, but failed to detect people using wheelchairs and parents pushing strollers. the drivers had to manually respond in those cases.

What's the best way that Safiya can improve the machine learning algorithm's ability to detect all pedestrians?

A. She can add videos of people using wheelchairs and strollers into the training data set (perhaps crowd-sourcing them if there are none already available).

B. She can double the size of the training data set by partnering with another company in the self-driving car industry.

C. She can program rules into the network about the shapes and movement patterns of wheelchairs and strollers.

The output of the given program will be:

"CPE"

This is because the program defines a subroutine named RESULT which takes a string parameter A$. The RESULT subroutine first calculates the length of the string A$ using the LEN() function and stores it in variable B. It then initializes a counter C to 1 and enters a loop that runs as long as C is less than or equal to B.

In each iteration of the loop, the program takes the character at the position specified by C in the string A$ using the MID$() function and appends it to a new string B$. The program then increments the counter C by 2 and continues with the next iteration of the loop.

Once the loop has been completed, the program prints the final value of B$, which will contain every other character of the input string A$. In this case, since the input string is "COMPUTER", the output will be "CPE".

A Class B IP address is a range of IP addresses that begins with the binary digits "10" and has a subnet mask of 255.255.0.0. When a /23 subnet mask is used with a Class B IP address, it means that 23 bits are used for the network portion of the address and the remaining 9 bits are used for the host portion.

To calculate how many bits were borrowed from the host portion of the address, we need to subtract the number of bits used for the network portion (23) from the total number of bits in the host portion (which is 16 bits in a Class B address). 16 - 23 = -7 This calculation gives us a negative number, which is not possible. It indicates that there has been an error in the calculation or that the subnet mask is invalid for a Class B IP address.Therefore, we can conclude that the question is incorrect or incomplete as it does not provide accurate information to determine how many bits were borrowed from the host portion of the address.

The output of executing the code segment will be (D) 5. Here's how the method works: It initializes a count variable to 0 and a curr variable to the last element of the input array.

It then iterates through the array and compares each element to the curr variable. If the element is greater than curr, count is incremented by 1. Otherwise, count is decremented by 1. After each comparison, curr is set to the current element. Finally, the method returns the count value. For the given input array [4, 14, 15, 3, 14, 18, 19], the method will compare each element to the previous one as follows: 4 < 19: count = -1  14 < 4: count = -2  15 > 14: count = -1  3 < 15: count = -2  14 < 3: count = -3  18 > 14: count = -2  19 > 18: count = -1  So the final count value is -1 - 2 - 1 - 2 + 1 - 2 - 1 = -6. However, the question asks for the absolute value of the count, which is 6, and since option B is not present, the correct answer is (D) 5.
