One of the questions in the "Top new questions this week" section of today's SO newsletter is Why is processing a sorted array slower than an unsorted array? which has a couple of close votes for being a duplicate. Does the criteria for putting questions in the newsletter filter out questions with close votes? Were the votes cast after the newsletter was composed?
It was obviously a mistake.
On a quick reading "Why is processing a sorted array slower than an unsorted array?" looks like a duplicate of "Why is processing a sorted array faster than an unsorted array?". Especially as many of us remember seeing the original question.
This has been sorted out now, and the question is reopened.
