D Even Parity Input: Standard Input Output: Standard Output We have a grid of size N x N. Each cell of the grid initially contains a zero(0) or a one(1). The parity of a cell is the number of 1s surrounding that cell. A cell is surrounded by at most…
一.Swift的枚举 枚举是一系相关联的值定义的一个公共的组类型,同时能够让你在编程的时候在类型安全的情况下去使用这些值.Swift中的枚举比OC中的枚举强大得多, 因为Swift中的枚举是一等类型,它除了可以定义枚举值外,还可以在枚举中像类一样定义属性和方法 1. 简单枚举定义和使用 //定义枚举,使用enum关键字 enum Method{ case Add case Sub case Mul case Div } //可以连在一起写,成员之间用","隔开 enum Compass…

一.概述 1.调用STM32库函数配置与直接配置寄存器 ① 直接配置寄存器 使用过51单片机的朋友都知道为了将IO口配置成某种特殊功能或者配置中断控制,我们先将需要如下步骤: 根据需要配置功能计算值---->直接写入寄存器 ② 调用STM32库函数配置 定义一个配置结构体变量---->根据配置功能依次给这个结构体变量的成员赋值----->将结构体变量的地址传入库函数,并调用STM32库函数实现配置 其中最后一个步骤的"调用STM32库函数",实际上就是将配置结果写入寄…
