Neste exercício, programe a função `logicread()` para receber um texto contendo os símbolos `&&` e `||`. Ela deve realizar a conversão dos mesmos em `and` e `or` respectivamente, quando houverem espaços brancos em ambos os lados dos símbolos (que devem ser mantidos). Outro detalhe é que esses símbolos não ocorrem no começo ou final das linhas. Com tudo funcionando, deve-se conseguir:\n",

    "**4)** Pela primeira vez a Escola Livre de Matemática, Filosofia e Linguística de Skyrim vai receber a Maratona de Expressões Regulares (regex) (RegExCon). A maratona acontece da seguinte forma: os participantes competem sempre contra 1 oponente. Um ganha um perde. No final, só o campeão restará. Em uma disputa os participantes recebem uma lista com várias expressões regulares e para cada uma os participantes devem calcular se várias palavras dadas são reconhecidas ou não por tal regex.\n",
    "\n",
    "Como membro da Escola Livre você está participando, e quer ganhar. Para garantir sua vitória, você deve escrever um programa para resolver o problema e deixá-lo rodando na sua Máquina Calculadora de Coisas Legais em casa. Como um mago, especialista em Alteração e Ilusão, você pode facilmente controlar sua máquina com a mente, então você consegue usar o programa durante a maratona. É proibido utilizar magia na maratona, mas coincidentemente a Escola de Winterhold vai sediar um Congresso de Magos, então você não precisa se preocupar, use sua magia.\n",
    "\n",
    "Uma expressão regular é utilizada para descrever uma linguagem (um conjunto de palavras). Considere que o alfabeto de todas linguagens neste problema é {a, b}.\n",
    "\n",
    "Uma regex R é válida se:\n",
    "\n",
    "    1) R é “a” ou “b”;\n",
    "    2) R é “(P.S)” onde P e S são expressões regulares;\n",
    "    3) R é “(P|S)” onde P e S são expressões regulares;\n",
    "    4) R é “(P*)” onde P é uma expressão regular.\n",
    "\n",
    "Expressões regulares podem ser aninhadas. Não há operação ternária com os operadores “.” e “|”, nem operação binária com o operator “*”. Palavras sempre começam com “(“ e terminam com “)”. O conjunto L de palavras reconhecidas por R é formado seguindo estas regras:\n",
    "\n",
    "    1) Se R é “(a)”, L = {a};\n",
    "    2) Se R é “(b)”, L = {b};\n",
    "    3) Se R é “(P.S)”, L = todas palavras que podem ser obtidas a partir da concatenação das palavras p e s, onde p é reconhecida por P e s por S;\n",
    "    4) Se R é “(P|S)”, L = união dos conjuntos de palavras reconhecidas por P e S;\n",
    "    5) Se R é “(P*)”, R reconhece a concatenação de 0 ou mais palavras reconhecidas por P.\n",
    "\n",
    "\n",
    "Em suma, você deve construir uma função que receba um texto no seguinte formato: a primeira linha contém uma regex (0 < tamanho da regex < 150). A próxima linha contém um inteiro P (1 ≤ P ≤ 100). Cada uma das próximas P linhas contém uma palavra (tamanho < 50) formada por 'a's e 'b's que representa a seguinte questão: “Esta palavra é reconhecida pela regex dada?”. Para cada questão descrita anteriormente, responda “Y” (sem aspas) se a resposta é “sim” ou “N” (sem aspas) se a resposta é “não”. Após implementar essa função chamada `maratona`, o seguinte bloco de códigos deve ser possível:\n",

locked alice been way down one side trying every door walked sadly down middle wondering ever get suddenly came upon little three legged table made solid glass nothing except tiny golden key alice first thought might belong one doors hall alas either locks large key small rate would open however second time round came upon low curtain noticed behind little door fifteen inches high tried little golden key lock great delight fitted alice opened door found led small passage much larger than rat hole knelt down looked along passage loveliest garden ever saw longed get dark hall wander among
