Lista de Exercícios para treinar Lógica de Programação.

I leave everyone in the community a list of exercises to train Programming Logic.
(I leave my resolution for each one, using the Java language)

Exercises

1 - Create an algorithm that reads the values of A, B, C and then prints the sum between A and B on the screen and shows whether the sum is less than C.

package org.example;
import java.util.Scanner;
public class Main {
    public static void main(String[] args) {
        System.out.println("Write a value of A:");
        Scanner integerScanner = new Scanner(System.in);
        int A = Integer.parseInt(integerScanner.next());
        System.out.println("Write a value of B:");
        int B = Integer.parseInt(integerScanner.next());
        System.out.println("Write a value of C:");
        int C =  Integer.parseInt(integerScanner.next());
        int sum = A + B ;

        if (sum <= C){
            System.out.println("The result of value A + B is: " + sum + ";\nThe sum of A + B is less or equal value C");
        }
        else{
            System.out.println("The result of value A + B is: " + sum + ";\nThe sum of A + B dont is less or equal value C");
        }
    }

2 - Create an algorithm to receive any number and print on the screen whether the number is even or odd, positive or negative.

package org.example;
import java.util.Scanner;
public class Main {
    public static void main(String[] args) {
        System.out.println("Write a number:");
        Scanner integerScanner = new Scanner(System.in);
        int number = Integer.parseInt(integerScanner.next());
        if (number >=0){
            if (number % 2 == 0){
                System.out.println("The number " + number + " is 'even' = par and positive");
            } else System.out.println("The number " + number + " is 'odd' = impar and positive");
        } else {
            if (number % 2 == 0){
                System.out.println("The number " + number + " is 'even' = par and negative");
            } else
                System.out.println("The number " + number + " is 'odd' = impar and negative");

        }
    }

3 - Make an algorithm that reads two integer values A and B, if the values of A and B are equal, you must add the two values,

otherwise you must multiply A by B. At the end of any of the calculations you must assign the result to a variable C and

print your value on the screen.

package org.example;
import java.util.Scanner;
public class Main {

    public static void main(String[] args) {
        System.out.println("Write your first value:");
        Scanner integerScanner = new Scanner(System.in);
        int A = integerScanner.nextInt();
        System.out.println("Write your second value:");
        int B = integerScanner.nextInt();
        int C;
        if (A == B){
            C = A + B;
            System.out.println("The sum off A + B is: " + C);
        } else {
            C = (A * B);
            System.out.println("The multiple of A x B is: " + C);
        }
    }
}

    public static void main(String[] args) {
        Scanner integerScanner = new Scanner(System.in);
        System.out.println("Write your number: ");
        int number = integerScanner.nextInt();
        int nextNumber = number + 1;
        int previousNumber = number - 1;
        System.out.println("The next number is: " + nextNumber);
        System.out.println("The previous number is: " + previousNumber);
    }

5 - Create an algorithm that reads the value of the minimum wage and the value of a user's salary, calculates how many minimum wages this

user wins and prints the result on the screen. (Base for minimum wage R$ 1,293.20).

package org.example;
import java.util.Scanner;
public class Main {
    public static void main(String[] args) {
        Scanner doubleScanner = new Scanner(System.in);
        System.out.println("Write your salario: ");
        double salarioMin = 1293.20;
        double salario = doubleScanner.nextDouble();
        double total = salario / salarioMin;
        System.out.printf("the salario is: %.2fx o salario min" , total);
    }
}

6 - Create an algorithm that reads any value and prints it on the screen with a 5% adjustment.

import java.util.Scanner;
public class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.print("Write a value: ");
        double a = scanner.nextDouble();
        double total = a *.05;
        double result = a + total;
        System.out.printf("the value with 5%% increase is: %.2f" , result);
    }

7 - Make an algorithm that reads two Boolean (logical) values and determines whether they are both TRUE or FALSE.

package org.example;
import java.util.Scanner;
public class Main {
    public static void main(String[] args) {
    Scanner scanner = new Scanner(System.in);
    System.out.print("Write a boolean value: ");
    boolean value1 = scanner.nextBoolean();
    System.out.print("Write other boolean value: ");
    boolean value2 = scanner.nextBoolean();

    if (value1 && value2){
        System.out.println("values are true");
    } else if (!value1 && !value2){
        System.out.println("values are false");
    } else {
        System.out.println("value are different");
    }

        Scanner scanner = new Scanner(System.in);
        System.out.println("Write your first value");
        int value1 = scanner.nextInt();
        System.out.println("Write your second value");
        int value2 = scanner.nextInt();
        System.out.println("Write your third value");
        int value3 = scanner.nextInt();
        int[] values = {value1, value2, value3};
        Arrays.sort(values);

        System.out.println("Values in descending order:");
        for (int i = values.length - 1; i >= 0; i--) {
            System.out.print(values[i] + " ");
        }
