Question

Дан массив D(7) определите минимальный элемент этого массива. Выведите на экран сам минимальный элемент и его индекс. Массив заполняется случайными числами от 16 до 40.

Answer 1

begin

 var a := ArrRandom(7, 16, 40); a.Println;

 var (ind, el) := a.Numerate.MinBy(x -> x[1]);

 Print('index:', ind, 'element:', el)

end.

Problem Analysis

To find the minimum element and its index in an array, we need to iterate through the array and keep track of the minimum element and its index as we go. We can initialize the minimum element and index with the first element of the array, and then compare it with the remaining elements. If we find a smaller element, we update the minimum element and its index. Finally, we output the minimum element and its index.

Solution

Here's the solution in JavaScript:

// Generate the array with random numbers between 16 and 40
const D = Array.from({ length: 7 }, () => Math.floor(Math.random() * (40 - 16 + 1)) + 16);

// Initialize the minimum element and its index with the first element of the array
let minElement = D[0];
let minIndex = 0;

// Iterate through the array starting from the second element
for (let i = 1; i < D.length; i++) {
  // If we find a smaller element, update the minimum element and its index
  if (D[i] < minElement) {
    minElement = D[i];
    minIndex = i;
  }
}

// Output the minimum element and its index
console.log(`The minimum element is ${minElement} at index ${minIndex}.`);

Explanation

1. We generate the array `D` with random numbers between 16 and 40 using the `Array.from()` method and the `Math.random()` function. 2. We initialize the minimum element and its index with the first element of the array (`D[0]`). 3. We iterate through the array starting from the second element (`i = 1`) using a `for` loop. 4. Inside the loop, we compare each element (`D[i]`) with the current minimum element (`minElement`). 5. If we find a smaller element, we update the minimum element and its index. 6. After the loop, we output the minimum element and its index using `console.log()`.

Example Output

Here's an example output of the code:

The minimum element is 18 at index 3.

Please note that the output will vary each time you run the code due to the random generation of the array.
