For the macro, it's one of the most commonly used ones by competitive programmers and it's quite simple -- You are missing the point. First, this is not a competitive programming site. Second, you are asking someone to look at your code, and having to figure out every time we see "loop(n)" what that means, regardless of how "simple" it is. This loses focus on looking at the flow of the program. Third, usage of such macros wouldn't pass any code review. — PaulMcKenzie 9 secs ago
