Задача 1:
1. Запросить у пользователя ввод целого числа, которое нужно получить как сумму чисел из массива.
2. Создать массив, запрашивая и сохраняя введенные пользователем целые числа.
3. Пройтись по массиву, сложить каждую пару чисел и проверить, равна ли их сумма числу, введенному пользователем.
4. Если сумма равна заданному числу, сохранить индексы этих чисел в новый массив.
5. Вывести новый массив с индексами.

Примерный код на Java:

import java.util.Scanner;

public class Main {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);

System.out.println("Введите число для суммы:");
int target = scanner.nextInt();

System.out.println("Введите размер массива:");
int n = scanner.nextInt();
int[] arr = new int[n];

for (int i = 0; i < n; i++) {
arr[i] = scanner.nextInt();
}

int[] indices = new int[2]; // создаем массив для индексов

for (int i = 0; i < n; i++) {
for (int j = i + 1; j < n; j++) {
if (arr[i] + arr[j] == target) {
indices[0] = i;
indices[1] = j;
break;
}
}
}

System.out.println("Индексы чисел, сумма которых равна " + target + ": " + indices[0] + ", " + indices[1]);
}
}


Задача 2:
1. Запросить у пользователя ввод строки.
2. Разбить строку на слова, подсчитать количество букв в первом и последнем слове.
3. Вывести количество букв для первого и последнего слова.

Примерный код на Java:

import java.util.Scanner;

public class Main {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);

System.out.println("Введите строку:");
String input = scanner.nextLine();

String[] words = input.split(" ");
int firstWordLength = words[0].length();
int lastWordLength = words[words.length - 1].length();

System.out.println("Количество букв в первом слове: " + firstWordLength);
System.out.println("Количество букв в последнем слове: " + lastWordLength);
}
}
