Create two Arrays A with 10 unsorted integer elements and B with 10 unsorted floatelements. Find the largest element in A and B and then sum both of them calling afunction SumAB() by reference. Sort A and B and then call another function StichAB()to merge B with A. Be careful about memory leakage.
Quicksort SPLIT (the 2-pointer algorithm covered in class) is applied to the integer array [4,3,5,7,9,2,1], using the first entry as the pivot. Show the series of item swaps that are performed in the split process, and the array after each of these swaps, up to and including the step of placing the pivot at its correct location. You only need to show the split of the original array, you are not required to continue working on the subarrays after the split.
Assume that empName and empID are two parallel arrays of size numEmp that hold employee data. Write a pseudocode algorithm that sorts the empID array in ascending ID number order (using any sort you wish), such that the two arrays remain parallel. That is, after sorting, for all indexes in the arrays, empName[index] must still be the name of the employee whose ID is in empID[index].
Write a program that will take a pointer to the array as input and calculate if the number on which currently pointer has any two number pair in the array (after that number); that sums equal to that number. For example, if we have array; [5,3,4,1,2] then it must return [5,3] as both have sum pair.Note: No subscript operator” [ ]” will be used during this task on pointerarithmetic allowed e.g. *(ptr+1).

You need to generate a (5x12) rain matrix (Rain[5][12]) that contains the average rainfall over 12 months for a 5 year period. You program should do the following steps: Create a 5x12 integer rainfall matrix Create a 5 element array of int pointers(int * Rain[5]) and assign each pointer to the address of the first element of each row Populate the elements of the matrix with pseudo-random numbers having a range from 0-100 Use the rand( ) function to generate your temperatures. The output of rand() should be mod with 100 (rand()%100) in order to get reasonable rainfall values. Init the random number generator with long seed = srand(67) This task should be performed by a function, void RainGen(int* Rain[ ], int R, int C), that populates all the matrix entries. After generating all rainfall matrix entries, print the entire matrix using the function, void Print(int* Rain[ ], int R, int C); Calculate the total monthly Rainfall per year for the entire five years. Use the following…
In python, how do you generate a distance matrix H where in each entry hij, the distance between row i and row j are stored, distance is computed by the inner product <x,y>C := xTCy, where the matrix C is a 3x3 matrix: [3 1 6 1 2 1 6 1 27]. The dataset is a 26x5 matrix and I need to find the distance using the above inner product between each row - I should end up with a 26x26 distance matrix H, where each diagonal entry (i=j) is 0.
Suppose that a company's employee data is stored in a matrix like the one in the image example: Each row of the matrix has four entries, representing the name, registration, sector, and telephone information of an employee, in that order. The number of lines depends on the number of employees. All matrix entries are in string format. Write a function that receives an array like the one in the example and performs a search by sector, that is, given a name of a sector of the company, the function returns the data of all employees of that sector. For example: searchSector(P,‘Contabilidade’) = [[‘Adalberto Ferreira’, ‘1091982’, ‘(21)99281-2983’],[‘FlaviaAmorim', '1128938', '(22)99273-9404']]where P is the matrix of the image example. If no record is found, the function should return to ‘No records found’ message.

Exercise 1: Write a main program that reads the elements of a 2 x 2 integer matrix, A, from the user. It then performs the following tasks: • prints the matrix row-by-row using a nested looping structure, • adds all matrix elements in row 0 using a looping structure and prints the sum. For example, for matrix, A| [i 3 A[2][2] = 7 9 The Sample Session will be as follows: CA Microsoft Visual Studio Debug Console Enter element at row 0 column 0: 1 Enter element at row e column 1: 3 Enter element at row 1 column 0: 7 Enter element at row 1 column 1: 9 The matrix entered by the user is: 13 7 9 Sum of row 0 elements: 4 C:\Users\User\source\repos \Project1\Debug\Project1.exe (process 52912) exited with code 0.

DESIGN YOUR OWN SETTING Task: Devise your own setting for storing and searching the data in an array of non-negative integers redundantly. You may just describe the setting without having to give an explicit algorithm to explain the process by which data is stored. You should explain how hardware failures can be detected in your method. Once you have described the setting, include the following to your answer: Write a pseudocode function to describe an algorithm where the stored data can be searched for a value key: if the data is found, its location in the original array should be returned; -1 should be returned if the data is not found; -2 should be returned if there is a data storage error Include a short commentary explaining why your pseudocode works Describe the worst-case and best-case inputs to your search algorithm Derive the worst-case and best-case running times for the search algorithm Derive the Theta notation for the worst-case and best-case running times
Assume that the maximum number of employees working in a company is 100 and all employees have personnel numbers (ID) between [1-999999]. Employees' numbers (IDs) will be stored in an array of size 100 . Assume that the ID of a personnel is 15426, then 15426 % 100 = 26 will be calculated and this ID will be assigned to the 26th index of the array. If an ID has already been assigned here, 15426 will be assigned to the 27th index of the array. If 27th index is also full, then an empty space must be searched by increasing the index number and the ID must be assigned when an empty space is found. (If the 99th index is reached when searching empty space, return to the index 0 and continue to search an empty space.) If all elements of the array are full, then the program must print an output indicating that "the array is full". The function that adds records should be given in the form below. This function returns the index number to which the ID is assigned. It must return -2 if the array…
