Step by step
Solved in 3 steps
- Pointers and references are fully equivalent True FalsePHP Write a reduce function Write a function reduce($arr, $func) that takes an array and a function as a parameter. The reduce function should apply the parameter function to each element of the array in succession to produce a single result. Note: the current result should always be the first parameter to the function and the next element of the array should always be the second parameter. You may not use the PHP function array_reduce in your solution. For example, the result of the following should be 10. function myMax($current, $new) { return $current < $new ? $new : $current; } $arr = array(10, 5, 3, 5, 1, 2, 5, 7, 4); print("Max: " . reduce($arr, 'myMax') .В.width; } { t = B.type; w = { T.type = C.type; T.width = C.width; } T → B C В > int { B.type = integer; B.width 4; } В — foat { B.type = float; B.width = 8; } { C.type = t; C.width = w; } C - [ num] C1 = array(num. value, C1.type); { C.type C.width = num. value x C1. width; }
- Task 3: Statistics using arrays: by java programming With the spread of COVID 19, the HR department in a company has decided to conduct some statistics among the employees in order to determine the number of infections according to some conditions. For each employee, they have to record the code, name, age, whether he/she was infected or no and the remaining days of leaves for him/her. You are requested to write the program that maintains the lists of details for the employees as mentioned above using the concept of arrays. The program repeats the display of a menu of services until the user decides to exit. 1. Start by initializing the employee details by reading them from the keyboard. 2. Repeat the display of a menu of 4 services, perform the required task according to the user’s choice and asks the user whether he/she wants to repeat or no. You need to choose one service from each category (‘A’,’B’,’C’,’D’) a. A. Display the total number of employees that were infected b. B.…The following array of structures is used to hold data of your IPC144 grade center strcut grades {char name[101]; unsigned final; unsigned total;} struct grades myClass[25]; Write a function that gets the class grades array as a parameter and prints the list of people who passed the course (a student passes a course if he/she passes the final as well as the total) and their total mark. The function should also print the class average at the end (based on the total marks) void printPassedAverage(struct grades myClass, int size) The output should be like this Students passed:--------------------- John Smith 85 Jane Doe 65 Roy Crowe 80 Julia Stuart 55 Rob Gates 60 Class average: 69def drop_uninformative_objects(X, y):# your code herereturn X_subset, y_subset # TEST drop_uninformative_objects functionA = pd.DataFrame(np.array([[0, 3, np.nan],[4, np.nan, np.nan],[np.nan, 6, 7],[np.nan, np.nan, np.nan],[5, 5, 5],[np.nan, 8, np.nan],]))b = pd.Series(np.arange(6))A_subset, b_subset = drop_uninformative_objects(A, b) assert A_subset.shape == (3, 3)assert b_subset.shape == (3,)
- A "generic" data structure cannot use a primitive type as its generic type. O True FalseLanguage: JAVA Script write a function 'keyValueDuplicates (obj) that takes an object as an argument and returns an array containing all keys that are also values in that object. Examples: obj1 = { orange: "juice", apple: "sauce", sauce: "pan" }; console.log(keyValueDuplicates (obj1)); // ["sauce"] obj2 = { big: "foot", foot: "ball", ball: "boy", boy: "scout"};console.log(keyValueDuplicates(obj2)); // ["foot", "ball", "boy"] obj3 = { pizza: "pie", apple: "pie" pumpkin: "pie"); console.log(keyValueDuplicates (obj3)); // [] *******************************************************************/function keyValueDuplicates (obj) { | // Your code here } /*****DO NOT MODIFY ANYTHING UNDER THIS LINE*********/ try { | module.exports = keyValueDuplicates; } catch (e) { | module.exports = null;}Question 9 ss In C Language : Annotate code, explain and show output Create a struct named Statistics that has two data members: a integer named totalSum and a double named average. Optionally, you can use a typedef to use another name for this struct. Write a function called ArrayStats() that takes two arguments, an array of integers and the size of the array. The function should return a Statistics object that contains the sum of the values in the array (stored in totalSum) and the average of the values in the array (stored in average). Call ArrayStats with two different array inputs, and print the average and sum for each array. Example Input: int intArr[] = {2, 4, 8,-9}; ArrayStats(intArr, 5); Example Output: Sum: 5 Average: 1.25
- Define the following structures: Manufacturer name : manufacturer’s name country : origin Vaccine vaccine name (e.g. Pfizer) : vaccine type (e.g MRNA) (e.g. $28.5) (e.g. 2 shots) name : type price : total price noofShot : total shots mf : Manufacturer type Declare an array called vaccineList that can store up to 10 Vaccine (refer to Question 4a) records. Initialize the first two elements with the following data: Vaccine Туре Price Shots Manu Origin $19.50 $13.60 Pfizer MRNA 2 Pfizer US Sinovac Whole Virus Sinovac Bio ChinaUser-defined ordinal types are beneficial when working with ordinal data. An associative array possesses many benefits and disadvantages.ISBNThis problem is slightly more difficult than the above problem. This one requires a data type that stores 10 digits. BackgroundPublishers and bookstores use a number system called the International Standard Book Number (ISBN) system to identify books. At the start of publication, each book is assigned a unique ISBN. An ISBN, once assigned, can never be re-used. Click here for detailed information on this numbering system.An ISBN consists of exactly 10 digits. The rightmost digit is the check digit. The check digit is validated modulo 11.• multiply each digit from the first to the ninth by a weight from 10 to 2 respectively (the first digit by 10, the second by 9,.., the ninth by 2).• the sum of the products plus the check digit should be divisible without remainder by 11.• if there is a remainder, the whole number is not a valid ISBN SpecificationsDesign a program that validates an ISBN. Your program keeps accepting a whole number and determining if that whole number is a valid…
