Tutoriais - Programação Orientada a Objetos(Deitel, 2003) Desenvolva um programa que reproduza o jogo adivinhe o número como segue: o programa escolhe um número para ser adivinhado selecionando um inteiro aleatório no intervalo de 1 a 1000. O programa apresenta a mensagem Adivinhe um número entre 1 e 1000. O jogador insere o palpite a ser analisado pelo programa. Se o palpite do jogador estiver incorreto, o programa deve exibir a mensagem Muito alto! Tente novamente! ou Muito baixo! Tente novamente! para auxiliar o jogador a se aproximar da resposta correta. Quando o usuário inserir a resposta correta, o programa deve apresentar a mensagem Parabéns! Você adivinhou o número!.
Desenvolva a solução solicitada, apresentando a modelagem do projeto em Unified Modeling Language (UML) e a sua implementação.
