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…
题目描述 在平面上有 n 个点(n <= 50),每个点用一对整数坐标表示.例如:当 n＝4 时,4个点的坐标分另为:p1(1,1),p2(2,2),p3(3,6),P4(0,7),见图一. 这些点可以用 k 个矩形(1<=k<=4)全部覆盖,矩形的边平行于坐标轴.当 k=2 时,可用如图二的两个矩形 sl,s2 覆盖,s1,s2 面积和为 4.问题是当 n 个点坐标和 k 给出后,怎样才能使得覆盖所有点的 k 个矩形的面积之和为最小呢.约定:覆盖一个点的矩形面积为 0:覆盖平行于坐标轴…
