BlackTDN :: LeetCode :: Resolvendo o Desafio "Palindrome Number" do LeetCode com XBase e TLPP

_Créditos das imagens: ChatGPT_ ### LeetCode :: **Resolvendo o Desafio "Palindrome Number" do LeetCode com XBase e TLPP** No mundo da programação, os desafios do LeetCode são uma excelente maneira de aprimorar nossas habilidades de codificação. Um desses é o desafio [**Palindrome Number** (Número Palíndromo)](https://leetcode.com/problems/palindrome-number/description/). Neste artigo, vamos explorar como resolvemos esse desafio utilizando XBase e TLPP (linguagens que possuem um poderoso conjunto de ferramentas para o desenvolvimento de soluções rápidas e eficientes). #### Descrição do Desafio O problema **Palindrome Number** exige que verifiquemos se um número inteiro é um palíndromo. Ou seja, o número deve ser lido da mesma forma de trás para frente como é lido da frente para trás. Exemplos de números palíndromos incluem: 121, 12321, etc. Já números como 123, 10, e -121 não são palíndromos, pois sua leitura invertida não é igual ao número original. A ideia é criar uma f...
