I just solved this problem yesterday and my code looked exactly like your second one. Even xs was the same, except I used a and b instead of x1 and x2 cause I always do that. But I actually like yours more. This is a very personal opinion, but I do like the second one more. I find it easier to read, but maybe that's just because I'm used to that style. And maybe you're more likely to have to rewrite it for a change, but that's kind of okay since there's less code there. On readability, here's how I'd read it out loud: Sort all the Xes from points. Return the max of the difference between two points that are next to each other. I find that quicker to put in my head than the equivalent parsing of the first solution, and exactly the intention of the code.
