Write down a recurrence relation for this version of QuickSort, and solve it asymp-totically. Show your work. Assume that the ti

torisob [31]

Answer:As in merge sort, the time for a given recursive call on an n-element subarray is Θ(n). In merge sort, that was the time for merging, but in quicksort it's the time for partitioning.

Explanation:

Worst-case running time:

When quicksort always has the most unbalanced partitions possible, then the original call takes cncnc, n time for some constant ccc, the recursive call on n-1n−1n, minus, 1 elements takes c(n-1)c(n−1)c, left parenthesis, n, minus, 1, right parenthesis time, the recursive call on n-2n−2n, minus, 2 elements takes c(n-2)c(n−2)c, left parenthesis, n, minus, 2, right parenthesis time, and so on. cn+c(n−1)+c(n−2)+⋯+2c=c(n+(n−1)+(n−2)+⋯+2)

=c((n+1)(n/2)−1)

The last line is because 1 + 2 + 3 +...... n is the arithmetic series

Best-case running time:

Quicksort's best case occurs when the partitions are as evenly balanced as possible: their sizes either are equal or are within 1 of each other. The former case occurs if the subarray has an odd number of elements and the pivot is right in the middle after partitioning, and each partition has (n-1)/ 2 elements. The latter case occurs if the subarray has an even number n of elements and one partition has n/2 elements with the other having n/2-1.In either of these cases, each partition has at most n/2 elements.

Using big-Θ notation, we get the same result as for merge sort: Θ(nlog2n)

What is a circular network.

Travka [436]

Answer:

A circular network happens when you have two (or more) routes to the same controller. Typically, the routes are BACnet/IP and BACnet/Ethernet and both are communicating on both networks. This could happen with BACnet MS/TP although it is rare.

No because the battery will die and it wont run anymore in other cases you would ask another person for help and connect cables to their car.

Write a while loop that continues to increment uservalue by 5 as long as uservalue is less than 0.

yan [13]

Using the knowledge in computational language in mathlab it is possible to write a code that while loop that continues to increment uservalue by 5 as long as uservalue is less than 0.

<h3>Writting the code:</h3>

<em>function </em><em>userValue </em><em>= IncreaseValue(userValue)</em>

<em>while(userValue<0)</em>

<em>userValue = </em><em>userValue</em><em>+5;</em>

<em>end</em>

<em>end</em>

<h3>How to run a code in MATLAB?</h3>

To run: If inside the Editor window: on the toolbar choose the Run icon; or in the Debug menu choose the Run option; or press F5. If the file is saved in memory, just type its name in the command window.
