Assume you have a sorting algorithm that you can use as a black box. Use the sorting algorithm to sort the input list. Now write

an algorithm to count the number of duplicates again. Analyze the time complexity of your algorithm in the worst-case (ignore the time complexity of sorting). Could you improve the worst-case time complexity of your algorithm compared to the previous question

Answer:

Algorithm explained below

Explanation:

Algorithm to check duplicate when list of element is sorted:

CheckDuplicate( Sorted list )

    initialize count = 0

    Repeat untill we reach on end of list :

            if next is not end of list and current element is equal to next element

                    count = count+1

                    increase the pointer to next untill a different element is found

end CheckDuplicate

Worst Case Time Complexity will be O(n). Because there is only one iteration over the list will be performed.

Yes We have improved the worst case time complexity compared to previous question.

Actually after applying sorting all the similar element to will be next to each other.Then we will start iterating one by one from one side and check which is similar to next.If a different element will be find then we will check whether it's next is similar to it or not.

eg. 1 1 1 2 2 2 4 4 4 we can check duplicate in one iteration.

Briefly explain what is net neutrality and why is it important today
ICE Princess25 [194]

Net neutrality also means that ISPs can't charge users access fees for particular websites. ... The goal of net neutrality is to ensure that businesses can compete freely on the internet without having to pay gatekeeper tolls. Without it consumers would look more like advertising segments than an open marketplace.

what is wrong with the following code? string s; system.out.println(s); group of answer choices the line, string s;, will cause
hodyreva [135]

The error in your Java program is described as follows:

You cannot print a string without setting its value.

<h3>How to print a string in Java?</h3>

There are multiple ways to print a string in a Java, but one of them is using the system.out.println(string) command, which prints the string and gives a new line.

However, for this method, and any other, the string has to be set before it is printed, which does not happen for this problem. There should be a line setting the string like the example:

s = "ABC";

Hence the correct option regarding the error is given as follows:

You cannot print a string without setting its value.
