An array may contain multiple duplicate values, as shown below. In order to design an algorithm with the best average performance to remove all duplicate values, which of the following data structures should be used?

Computer Science Done in Perl. Someone gave me a wrong/incomplete answer. Write a function, hashsum, which takes a hash reference as its first argument and an array reference as its second argument. The function should take the elements of the array and use them as keys in the hash. The values in the hash corresponding to the keys in the array should be totaled, and the sum should be returned to the user. If a key passed in the array does not exist in the hash, ignore it. Write a sample program to call this function.
I have the following JAVA CODE: deleteButton.addActionListener((e -> {int row= table.getSelectedRow();if (row>= 0) {String uName = (String) table.getValueAt(selectedRow, 0);JSONArray array= readJSONFile("sample.json");for (int i = 0; i < deleteArray.size(); i++) {JSONObject obj = (JSONObject) deleteArray.get(i);String username= (String) obj.get("username");if (uName.equals(currentUName)) {array.remove(i);tableModel.removeRow(row);break;}}}}));} Please make a code that will delete the details on the selected row on the JSON file.
Perform the following operations utilizing c++ code.N.b array size to be used is ten.a)enqueue() i.e enqueue the list; Two,three,four,five,six,seven and eight and after display enqued list.b)dequeue() i.e delete or remove any two elements in the queue in a) above and after display the updated queue after deletion.c)ISfull() i.e Display if the queue is Full or not.d)Isempty() i.e Display if the queue is Empty or not.e)print() i.e print the final list of the elements of the Queue after performing tasks of a) - d).

Write the code of MergeSort algorithm using JAVA programming language. Assume your array continues 8 unsorted numbers. Hint: Array[] = 56, 4 , 44, 6, 5, 32, 60, 2 Change the array as you want.
8.12 LAB: Binary search Binary search can be implemented as a recursive algorithm. Each call makes a recursive call on one-half of the list the call received as an argument. Complete the recursive method binarySearch() with the following specifications: Parameters: a target integer an ArrayList of integers lower and upper bounds within which the recursive call will search Return value: the index within the ArrayList where the target is located -1 if target is not found The template provides main() and a helper function that reads an ArrayList from input. The algorithm begins by choosing an index midway between the lower and upper bounds. If target == integers.get(index) return index If lower == upper, return -1 to indicate not found Otherwise call the function recursively on half the ArrayList parameter: If integers.get(index) < target, search the ArrayList from index + 1 to upper If integers.get(index) > target, search the ArrayList from lower to index - 1…
Requirements: Use Java Programming only. Show screenshots of your work. this is the second time I posted this since the previous answer is very wrong. 6. Write method public static int linearSearch(int [] arr, ine key) which returns the largest index such that arr[index] matches the key. If there is match, returns -1. 7. Write method public static double average(int [] arr) which returns the average of all elements in given array arr. Assume that arr has length at least 1. 8. Write method public void crazyPrint(String sentence, int n) which print out the given sentence n times. Assume n is positive integer.
Which of the following structures would be the most efficient to use if you wanted to establish a priority queue for quick retrieval? Choose one: a. a doubly linked list that is sorted O b. array of ordered elements a. unordered singly linked list b. unordered singly linked list c. unordered singly linked O d. an unsorted array
Retrieving a value using its associated key can be accomplished using anindexer, which works just like an indexer for an array. A key is passed in asthe index value, and the value associated with the key is returned, unless thekey doesn’t exist, in which a null is returned.Write short code segment demonstrates how this technique works:
Create a program (or set of programs) which accomplish the following for each complex data type (list,tuple,set,frozenset, dictionary): create the item with at least 4 elements Append an element Remove an element Insert an element in the middle somewhere Append another array of the same data type Append another array of a different data type (for example, if you have a dictionary, append a set or tuples And do the following: Output the results after each step. Report and explain any errors (if a line of code generates an error, comment it out along with a comment on what the error was and your reasons for that error) Create a range of negative numbers Create a range of positive even numbers Insert a range into each data type that would allow it Please explain each error you ran into
