Write a program to read as many test scores as the user wants from the keyboard (assuming at most 50 scores). Print the scores in (1) original order, (2) sorted from high to low (3) the highest score, (4) the lowest score, and (5) the average of the scores. Implement the following functions using the given function prototypes: void displayArray(int array[], int size) - Displays the content of the array void selectionSort(int array[], int size) - sorts the array using the selection sort algorithm in descending order. Hint: refer to example 8-5 in the textbook. int findMax(int array[], int size) - finds and returns the highest element of the array int findMin(int array[], int size) - finds and returns the lowest element of the array double findAvg(int array[], int size) - finds and returns the average of the elements of the array

Consider the following relations: Emp(eid: integer, ename: varchar, sal: integer, age: integer, did: integer) Dept(did: integer, budget: integer, floor: integer, mgr_eid: integer) Salaries range from $10,000 to $100,000, ages vary from 20 to 80, each department has about five employees on average, there are 10 floors, and budgets vary from $10,000 to $1 million. You can assume uniform distributions of values. For each of the following queries, which of the listed index choices would you choose to speed up the query.1. Query: Print ename, age, and sal for all employees. A) Clustered hash index on fields of Emp. B) Unclustered hash index on fields of Emp. C) Clustered B+ tree index on fields of Emp. D) Unclustered hash index on fields of Emp. E) No index.2. Query: Find the dids of departments that are on the 10th floor and have a budget of less than $15,000. A) Clustered hash index on the floor field of Dept.B) Unclustered hash index on the floor field of Dept. C) Clustered B+ tree index on fields of Dept. D) Clustered B+ tree index on the budget field of Dept. E) No index.

5.14 Write a version of the inner product procedure described in Problem 5.13 that uses 6 1 loop unrolling. For x86-64, our measurements of the unrolled version give a CPE of 1.07 for integer data but still 3.01 for both floating-point data. A. Explain why any (scalar) version of an inner product procedure running on an Intel Core i7 Haswell processor cannot achieve a CPE less than 1.00. B. Explain why the performance for floating-point data did not improve with loop unrolling.

Write a static method named contains that accepts two arrays of integers a1 and a2 as parameters and that returns a boolean value indicating whether or not a2's sequence of elements appears in a1 (true for yes, false for no). The sequence of elements in a2 may appear anywhere in a1 but must appear consecutively and in the same order. For example, if variables called list1 and list2 store the following values: int[] list1 = {1, 6, 2, 1, 4, 1, 2, 1, 8}; int[] list2 = {1, 2, 1}; Then the call of contains(list1, list2) should return true because list2's sequence of values {1, 2, 1} is contained in list1 starting at index 5. If list2 had stored the values {2, 1, 2}, the call of contains(list1, list2) would return false because list1 does not contain that sequence of values. Any two lists with identical elements are considered to contain each other, so a call such as contains(list1, list1) should return true.

This represents a group of Book values as a list (named books). We can then dig through this list for useful information and calculations by calling the methods we're going to implement. class Library: Define the Library class. def __init__(self): Library constructor. Create the only instance variable, a list named books, and initialize it to an empty list. This means that we can only create an empty Library and then add items to it later on.

Write the method addItemToStock to add an item into the grocery stock array. The method will: Insert the item with itemName add quantity items to stock. If itemName is already present in stock, increase the quantity of the item, otherwise add new itemName to stock. If itemName is not present in stock, insert at the first null position in the stock array. After the insertion all items are adjacent in the array (no null positions between two items). Additionally, double the capacity of the stock array if itemName is a new item to be inserted and the stock is full.
