Nettet要求 ：判断一个数 x 是否是 int 型最小值 tmin 。 思路 ： tmin 有性质 ： tmin + tmin = 0. 所以 tmin = ~tmin+1. 但是要 特判去掉同样满足的 0 [0x0] 。 判断相等用异或，异或值为0则相等。 /* * isTmin - returns 1 if x is the minimum, two's complement number, * and 0 otherwise * Legal ops: ! ~ & ^ + * Max ops: 10 * Rating: 1 */ int isTmin(int x) { return !( … NettetAbsVal.make（x） 而不是 AbsVal（x） 这是一个非常主观的观点。在不同的语言中，人们通常倾向于使用描述性名称而不是重载定义，因为它们往往会引入歧义。你的案子就是这样一个完美的例子. 因此， AbsVal.make（x） 是适合您情况的正确方法。尽管我更愿意将 …
