2The second. One operation goes faster then two, but some compilers may optimize it, so care about readability first, just optimize code that isnt running smooth. Not to note that the second one is three bytes shorter!! :/ ;) – Jonas Wilms Jul 28 '17 at 08:43

1same, prefer 2nd, as there are less brackets – Vitaliy Moskalyuk Jul 28 '17 at 08:44

I prefer the second because I think it's more legible – Vasileios Pallas Jul 28 '17 at 08:46

Hint: Under what conditions, if any, is a test for equality faster or slower than a test for inequality? – Bathsheba Jul 28 '17 at 08:46
