To cut a n centimeter long gold bar into two pieces costs $n. When a gold bar is cut into many
pieces, the order in which the cuts occur can affect the total amount of costs. For example, to cut a
20 centimeter gold bar at length marks 2, 8, and 10 (numbering the length marks in ascending order
from the left-hand end, starting from 1). If the cuts to occur in left-to-right order, then the first cut
costs $20, the second cut costs $18 (cutting the remaining 18 centimeter bar at originally length
mark 8), and the third cut costs $12, totaling $50. If the cuts to occur in right-to-left order, however,
then the first cut costs $20 time, the second cut costs $10, and the third cut costs $8, totaling $38.
In yet another order, the first cut is at 8 (costing $20), then the 2nd cut is at 2 (costing $8), and

Answers

Answer 1

Dynamic Programming: To cut a n centimeter long gold bar into two pieces costs $n. The order in which the cuts occur can affect the total amount of costs. The optimal solution can be formulated with a recursive relation. A bottom-up algorithm can be designed to calculate the lowest cost for a sequence of cuts. The complexity of the algorithm is O(m*n).

The following algorithm can print out a sequence of cuts that achieves the lowest cost:
1. Create an array M[1..n] that stores the optimal cost.
2. Set M[0] = 0 and M[1] = 0.
3. Loop through C[1..m] and set M[i] = min{M[j] + c[j]}, where i is the current cut and j is the previous cut.
4. Finally, return M[n], which contains the lowest cost for a sequence of cuts.
By using this algorithm, the lowest cost for a sequence of cuts can be calculated in a dynamic programming approach.

Which of the following statements about the guarding against overestimating variable consideration under U.S. GAAP and IFRS is true?
Under IFRS, sellers only include an estimate of variable consideration to extent it is "probable" that a significant reversal of revenue recognized to date will not occur.
Under U.S. GAAP, sellers only include an estimate of variable consideration to extent it is "probable" that a significant reversal of revenue recognized to date will not occur.
U.S. GAAP and IFRS convey the same likelihood with regards to the uncertainty associated with the variable consideration.

Answers

The statement  is true because regarding U.S. GAAP and IFRS when it comes to guarding against overestimating variable consideration is that "Under IFRS, sellers only include an estimate of variable consideration to extent it is "probable".

IFRS requires that estimates of variable consideration be included only when the likelihood of significant reversal of revenue is “probable”, and this is a stricter standard than the “reasonably possible” standard under U.S. GAAP.

Under U.S. GAAP, estimates of variable consideration are only included when the amount of the estimate is both “reasonably possible” and “probable”. Therefore, U.S. GAAP and IFRS do not convey the same likelihood when it comes to the uncertainty associated with the variable consideration.

Under IFRS, the seller must be more certain that there will not be a significant reversal of revenue before including the estimate, while under U.S. GAAP, the seller only needs to be reasonably certain that there is a possibility of a significant reversal.

Answers

The best algorithm to use for finding the insertion position of a new item in the linked list studentList.curNodeA = curNodeB is a linear search algorithm. A linear search algorithm is a simple search algorithm that looks for a value within a list by sequentially checking each element of the list until it finds the desired element or reaches the end of the list. In this case, the algorithm would start at the beginning of the studentList.curNodeA, and then check each node until it finds the desired insertion position.


Once the algorithm finds the desired insertion position, it would then insert the new item into the list, either at the beginning, middle, or end. To insert at the beginning, the algorithm would shift all the other elements down and make room for the new item. To insert at the middle, the algorithm would again shift all the other elements down, while making room for the new item. And to insert at the end, the algorithm would simply append the new item onto the end of the list.

To summarize, the best algorithm to use for finding the insertion position of a new item in the linked list studentList.curNodeA = curNodeB is a linear search algorithm. This algorithm can search for the desired insertion position and then insert the new item at the beginning, middle, or end of the list as needed.

Which of the following lists the measuring devices that are needed to determine the change in momentum of the cart? Timer, mass balance, and meterstick.

Answers

Option-A : The measuring devices that are needed to determine the change in momentum of the cart are Timer, Motion Sensor, and Cart.

Momentum is the product of an object's mass and its velocity. It is denoted by the letter p and is expressed in units of kilogram-meters per second (kg · m/s). Momentum is a vector quantity, which means that it has both magnitude and direction. The direction of the momentum is the same as the direction of the velocity.The change in momentum of an object is determined by applying the principle of conservation of momentum.

According to the principle, if two objects interact, their combined momentum will remain constant as long as no external forces act on them. In other words, the total momentum of the system remains constant in the absence of external forces. Therefore, the momentum of one object can be used to determine the momentum of another object after a collision.The measuring devices that are needed to determine the change in momentum of the cart are Timer, Motion Sensor, and Cart. Thus,the correct answer is option-A:Timer.

FILL IN THE BLANK. In the Reno TCP when TCP enters the fast recovery if a new (non-duplicate) ACK arrives, TCP _____.

Answers

In the Reno TCP, when TCP enters the fast recovery if a new (non-duplicate) ACK arrives, TCP increments the congestion window by 1 segment instead of 1/2 segment.

The Reno TCP was the first modification of TCP that addressed congestion. It replaces the slow start and congestion avoidance algorithms with a more aggressive algorithm that speeds up the recovery process when packet loss is detected in the network. The Reno TCP is able to detect the loss of a packet by the receipt of three duplicate acknowledgments, as it believes that the sender has transmitted a packet that has been lost. The Reno TCP then changes to fast recovery mode when it detects the third duplicate acknowledgement.

The Reno TCP is an enhancement to the TCP congestion avoidance algorithm that improves its ability to handle congestion in the Internet. It is a variant of TCP that is designed to cope with network congestion by quickly responding to lost packets, rather than relying on the slow, steady approach of TCP's congestion avoidance algorithm. The Reno TCP is able to detect the loss of a packet by the receipt of three duplicate acknowledgments, as it believes that the sender has transmitted a packet that has been lost.

This is because the algorithm is performing an operation that takes an amount of time that is proportional to 2 raised to the power of N. For example, if N is 5, the algorithm will take 2^5 = 32 time units. If N is 10, the algorithm will take 2^10 = 1024 time units.The Big O cost for the following in the worst case: O(N^2)The time complexity of O(N^2) means that the time taken by the algorithm will increase quadratically with the size of the input data.

Answers

The following circuit connects the output of a comparator (U1A) to an LED (D1). The condition is correct.

To determine if the condition is correct, we must examine the circuit and the functionality of the components. U1A is a comparator, meaning it takes two inputs and compares them. If the input voltage of U1A is higher than the reference voltage, U1A's output will be high (1). D1 is an LED, meaning when it is activated it will produce light. In this circuit, D1 is connected to U1A's output. Therefore, if U1A's output is high, the LED will be activated, and if U1A's output is low, the LED will not be activated.

To determine if the condition is correct, we must consider the logic of the circuit. If U1A's input voltage is higher than the reference voltage, U1A's output will be high and the LED will be activated. Therefore, the given condition is correct.

Explanation:

The program creates an empty list called values, and then uses a for loop to request five integer values from the user using the input() function. The int() function is used to convert the input values to integers, and the append() method is used to add each value to the values list.

After all five values have been entered, the program uses the set() function to create a set of the values. A set is an unordered collection of unique elements, so if there are any duplicate values in the original values list, they will be removed when the set is created. The program then compares the length of the original values list to the length of the set. If the lengths are not equal, it means there were duplicates in the original list, and the program prints "DUPLICATES". Otherwise, the program prints "ALL UNIQUE".

What BEST describes the difference between copyrighted graphics and written
works?

Answers

Answer:

the main difference between copyrighted graphics and written works is that copyrighted graphics are protected by copyright law, while written works are protected by both copyright and intellectual property law. Copyright law grants exclusive rights to the author of the work (such as the right to reproduce or distribute the work) while intellectual property law protects the expression of ideas.

Given the following values of arr and the mystery method, what will the values of arr be after you execute: mystery()? private int[] arr - (-17, -14, 3, 9, 21, 34); public void mystery() for (int i = 0; i < arr.length / 2; i += 2) arr[i] = arr[i]. 2;
A. {-34, -28, 6, 18, 42, 68}
B. {-17, -14, 3, 18, 21, 34}
C. {-34, -28, 6, 9, 21, 34)
D. {-34, -14, 6, 9, 21, 34}
E. {-34, -14, 6, 9, 42, 34}

Answers

The final value of arr will be {-8, -14, 1, 9, 10, 34}, which is closest to option B: {-17, -14, 3, 18, 21, 34}. Therefore, the answer is option B.

The mystery method is dividing the length of the array by 2 and iterating over the array by incrementing i by 2 in each iteration. In each iteration, it's updating the value at index i to be half of its current value.

Starting with the given values of arr: {-17, -14, 3, 9, 21, 34}

In the first iteration, i = 0, and arr[0] will be updated to -8.5, but since it's an integer array, it will be rounded down to -8.

After the first iteration: {-8, -14, 3, 9, 21, 34}

In the second iteration, i = 2, and arr[2] will be updated to 1.5, but since it's an integer array, it will be rounded down to 1.

After the second iteration: {-8, -14, 1, 9, 21, 34}

In the third iteration, i = 4, and arr[4] will be updated to 10.5, but since it's an integer array, it will be rounded down to 10.

After the third iteration: {-8, -14, 1, 9, 10, 34} Option B.
