The computing system that  can process large datasets when multiple devices are combined because of the additional memory and storage provided is c. Parallel

A parallel computing system can process large datasets when multiple devices are combined. Parallel computing involves dividing a computational task into smaller subtasks that can be executed simultaneously on multiple processors or devices. By distributing the workload across multiple devices, parallel computing can leverage the additional memory and storage provided by these devices to handle large datasets and perform computations in a more efficient and timely manner.

In a parallel computing system, each device works on its assigned portion of the dataset, and the results are combined or aggregated to produce the final output. This approach allows for faster processing, increased computational power, and enhanced scalability compared to sequential or incremental computing systems.

While dispersed and incremental computing methods may also involve distributed systems or incremental processing of data, they do not necessarily focus on leveraging multiple devices for increased memory and storage. Sequential computing, on the other hand, processes data one step at a time using a single processor or device and may not be suitable for efficiently processing large datasets.

An exchange system with occasional government Intervention is known as a managed float exchange rate system

An exchange system with occasional government intervention is known as a managed float exchange rate system. In this system, a country's currency value is determined primarily by market forces of supply and demand, with central banks or governments stepping in from time to time to influence or manage the exchange rate.In a managed float exchange rate system, the central bank may intervene by buying or selling the domestic currency in the foreign exchange market. This action can either strengthen or weaken the domestic currency relative to other currencies, depending on the intervention's objective.The primary purpose of a managed float is to maintain exchange rate stability and prevent excessive fluctuations that may harm a country's economy. Government intervention usually occurs when the central bank or government perceives the market-driven exchange rate as too high or too low, which may negatively impact trade balances, inflation, or overall economic growth.A managed float exchange rate system offers a balance between the two extremes of fixed and pure floating exchange rate systems. It allows for a certain degree of market determination while still enabling governments to intervene and stabilize the currency when necessary, aiming for a more stable and predictable economic environment.In a managed float exchange rate system is an exchange system where market forces primarily determine the currency value, but occasional government intervention is employed to maintain exchange rate stability and minimize potential negative economic impacts.

The baseline estimate of Alice's rating for Animal Farm would be 3.4 - 0.4 + 0.7 = 3.7 stars.

Matrix factorization is a popular technique used in recommendation systems to predict user ratings for items. It decomposes the rating matrix into two smaller matrices, one for users and one for items, with a lower dimension. This approach allows for more efficient and accurate recommendations by identifying latent factors that contribute to user-item interactions.

To estimate Alice's rating for Animal Farm, we can use the baseline approach, which involves adding a user-specific bias and an item-specific bias to the global mean rating. The user-specific bias accounts for the tendency of a particular user to rate items higher or lower than the global average, while the item-specific bias accounts for the tendency of a particular item to receive higher or lower ratings than the global average.

To calculate Alice's user-specific bias, we first need to calculate her average rating deviation from the global mean. Given that Alice's average rating is 0.4 stars lower than the global average, her user-specific bias would be -0.4.

Next, we need to calculate the item-specific bias for Animal Farm. Given that its average rating is 0.7 stars higher than the global average, the item-specific bias for Animal Farm would be 0.7.

Finally, we can estimate Alice's rating for Animal Farm by adding the global mean rating, the user-specific bias, and the item-specific bias together. Thus, the baseline estimate of Alice's rating for Animal Farm would be 3.4 - 0.4 + 0.7 = 3.7 stars.

Overall, the baseline approach is a simple yet effective method for predicting user ratings in recommendation systems. It takes into account the user and item-specific biases and the global mean rating to provide a personalized estimate of user ratings for items.

The given algorithm merges the arrays in a sequential order, starting with the first two arrays, then merging the result with the third array, and so on until all arrays are merged.

The time complexity of this algorithm can be expressed as O(kn log n), where k is the number of arrays and n is the total number of elements in all arrays.

The reason behind this time complexity is that merging two arrays of size n requires O(n log n) time complexity, as it involves a divide-and-conquer approach. Therefore, merging k arrays requires k-1 merge operations, and the time complexity for each merge operation is O(n log n). Thus, the overall time complexity of the algorithm is O((k-1)n log n), which simplifies to O(kn log n).

It's important to note that this algorithm assumes that all arrays are sorted beforehand. If the arrays are unsorted, additional time complexity would be required to sort them before the merging process can begin.
