Question

Дан массив из 15 элементов, значения которых выводятся случайным образом из диапазона [-6,56]. Найти элементы большие 31, вычислить суммы элементов. Вывести массив в столбец.

Answer 1

##

var a:= ArrRandom(15, -6, 56);

a.Println;

a.Where(x->x>31).Println;

a.Sum.Print;

Answer 2

Task Breakdown

To solve this problem, we need to perform the following steps: 1. Generate an array of 15 random elements within the range [-6, 56]. 2. Find the elements greater than 31 and calculate their sum. 3. Display the array in a column.

Generating Random Array

To generate an array of 15 random elements within the range [-6, 56], we can use the following JavaScript code: ```javascript let randomArray = Array.from({length: 15}, () => Math.floor(Math.random() * (56 - (-6) + 1)) + (-6)); ``` This code creates an array of 15 elements, each containing a random number within the specified range.

Finding Elements Greater Than 31 and Calculating Their Sum

We can use the `filter` method to find the elements greater than 31 and then use the `reduce` method to calculate their sum. Here's the JavaScript code to achieve this: ```javascript let elementsGreaterThan31 = randomArray.filter(element => element > 31); let sumOfElementsGreaterThan31 = elementsGreaterThan31.reduce((sum, element) => sum + element, 0); ``` In this code, `elementsGreaterThan31` contains all the elements greater than 31, and `sumOfElementsGreaterThan31` stores their sum.

Displaying the Array in a Column

To display the array in a column, we can use a simple loop to log each element on a new line. Here's the JavaScript code for this: ```javascript randomArray.forEach(element => console.log(element)); ``` This code logs each element of the array on a new line, effectively displaying the array in a column.
