In the CREW PRAM model, a parallel algorithm to determine the median of a set of numbers can be designed by dividing the set into smaller sub-sets, finding the medians of each sub-set, and then recursively finding the median of the medians.
This algorithm has a run time efficiency of O(log n) and a cost efficiency of O(n), where n is the size of the input set.
In the CRCW PRAM model, a parallel algorithm to determine the median of a set of numbers can be designed by using a quicksort-like approach. Each processor is assigned a portion of the input set, and they perform partitioning and comparison operations to find the median. Write conflicts can be resolved by using a priority mechanism, where processors with higher priorities overwrite the values of lower-priority processors. This algorithm has a run time efficiency of O(log n) and a cost efficiency of O(n), where n is the size of the input set.
In the CREW PRAM model, the algorithm can be designed as follows:
Divide the input set into smaller sub-sets of equal size.
Each processor finds the median of its sub-set using a sequential algorithm.
Recursively find the median of the medians obtained from the previous step.
This algorithm has a run time efficiency of O(log n) because each recursive step reduces the input size by a factor of 2, and a cost efficiency of O(n) as it requires n processors to handle the input set.
In the CRCW PRAM model, the algorithm can be designed as follows:
Each processor is assigned a portion of the input set.
Processors perform partitioning operations based on the pivot element.
Comparisons are made to determine the relative positions of the medians.
Write conflicts can be resolved by assigning priorities to processors, where higher-priority processors overwrite lower-priority processors.
This algorithm has a run time efficiency of O(log n) because it performs partitioning recursively, and a cost efficiency of O(n) as it requires n processors to handle the input set.
In summary, both the CREW PRAM and CRCW PRAM models provide efficient parallel algorithms for determining the median of a set of numbers. The CREW PRAM model achieves efficiency with a divide-and-conquer approach, while the CRCW PRAM model employs a priority-based write conflict resolution mechanism during the quicksort-like partitioning process. Both algorithms have a run time efficiency of O(log n) and a cost efficiency of O(n).

(exemplī gratia: the device consumed 5 millijoules with the microphone operating for 1 second and the screen for 0.5 seconds.) your goal is to calculate the energy consumed per second by each component on the device. you will do this by setting up and solving a linear system.you are given a python dictionary called test data containing measurements from 10 different tests. each test is stored as a python list of tuples (e.g. [('led0', 0.58), ('screen', 0.24), ('energyconsumed', 1.2), ...]). the tuple with first entry equal to 'energyconsumed' is the energy consumed by the device on that test. the other tuples indicate the length of time each component operated.you are also given a python list of the component ids called components. using these two inputs, build a linear system to solve for the rate of energy use of each component. you may use numpy.linalg.solve to solve your linear system. return power usage with entries corresponding to the same order as they show up in components (i.e. if 'screen' is the first string in components then the first entry of power usage should be the amount of energy per second that 'screen' consumes).
:A linear system can be set up to solve for the rate of energy use of each component using the given data. We know that the energy consumed per second by each component

A python list of the component ids called components is also given. Using these two inputs, we can build a linear system to solve for the rate of energy use of each component. The rate of energy use of each component can be calculated by dividing the energy consumed by the component with the time duration for which it operated on a given test.

2. briefly explain how does it reduce the response time of query processing using b tree (or b tree) in a data base?
B-tree is a data structure that is commonly used in database management systems to store and organize large amounts of data. It reduces the response time of query processing by allowing for efficient search and retrieval of data.
B-trees are balanced trees, meaning that the height of the tree is minimized and the number of accesses to the disk is reduced. This makes it easier and faster to search for data because fewer disk accesses are required. B-trees are also designed to have a large branching factor, which means that each node can contain many keys and pointers to child nodes.
When a query is executed, the database system can quickly navigate through the B-tree to find the data that matches the query criteria. This is because the B-tree is organized in such a way that data is sorted and stored in a predictable order, making it easy to locate specific information quickly. Overall, the use of B-trees in database management systems helps to reduce the response time of query processing by enabling fast and efficient search and retrieval of data.

The starter code uses an if-else chain to add a bit (1) when the up arrow is pressed, and a bit (0) when the down arrow is pressed.
