Question

Составьте программу, которая заполняет массив A[1..10] случайными целыми числами в диапазоне от -20 до 20, затем меняет местами первый элемент с максимальным элементом. Выведите на экран исходный и полученный массивы.

Answer 1

Const
 n=10;
var
 a:array[1..n] of integer;
 i, MAX,t:integer;
begin
 randomize;
 writeln('Исходный массив:');
 for i:=1 to n do
  begin
   A[i]:=random(40)-20;
   writeln(a[i]);
  end;
 MAX:=-20-1;
 for i:=1 to n do
  if A[i]>MAX
   then
     MAX:=A[i];
 t:=A[1];         //Замена
 A[1]:=MAX;
 MAX:=t;
 Writeln('Готовый массив:');
 for i:=1 to n do
  writeln(A[i]);
end.

Answer 2

Program to Fill and Swap Elements in an Array

Here is a program in Python that fills an array `A` with random integers in the range from -20 to 20 and then swaps the first element with the maximum element:

import random

# Function to fill the array with random integers
def fill_array(arr):
    for i in range(len(arr)):
        arr[i] = random.randint(-20, 20)

# Function to swap the first element with the maximum element
def swap_first_with_max(arr):
    max_index = arr.index(max(arr))
    arr[0], arr[max_index] = arr[max_index], arr[0]

# Create an array of size 10
A = [0] * 10

# Fill the array with random integers
fill_array(A)

# Swap the first element with the maximum element
swap_first_with_max(A)

# Print the original and modified arrays
print("Original Array:", A)
print("Modified Array:", A)

This program uses the `random.randint()` function from the `random` module to generate random integers in the specified range. The `fill_array()` function fills the array `A` with random integers, and the `swap_first_with_max()` function swaps the first element with the maximum element in the array.

Please note that the program assumes you have Python installed on your system. If you don't have Python installed, you can download and install it from the official Python website.
