El algoritmo toma una cadena como entrada y hace lo siguiente para validar el número de la tarjeta de crédito: • Ignora todos los espacios. Rechaza ser 1 +4 = 5. • Suma todos los dígitos, no duplicados y duplicados. • El número de la tarjeta de crédito es válido si la suma termina en 0. El código proporcionado ofrece una implementación errónea

Por que elas são definidas como macros e no que elas se expandem não é especialmente crítico. O curso não cobre a definição de macros, mas uma seção posterior descreverá o uso de macros Luhn é usado para validar números de cartão de crédito. O algoritmo recebe uma string como entrada e faz o seguinte para validar o número do cartão de crédito: • Ignore todos os espaços. Rejeite números

upgraded in the process of upgrading the Operator, or • Operand can be upgraded as part of changing the CR • Operator understands how to upgrade older versions of the Operand, managed previously by an older Operator conveys inability to manage an unsupported version of the Operand in the status section of the CR Lifecycle features • Operator provides the ability to create backups of the Operand • Operator is 为目标，以便整个过程更加接近实际的 Operator 开发 技能点： 1. 熟悉 kubebuilder operator 工程结构 2. 熟悉 K8s Declaretive API 如何设计 3. 熟悉 CR（custom resource）相关事件如何获取 4. 熟悉 Operator Control Loop（即 Reconcile 函数） 如何实现 5. 熟悉如何生成二级资源（Managed Resource）
