Yeowch! Mine (g034.d) shows up as the second red dot from the left. I submitted a quick pseudocode answer without any research in an effort to mimic interview whiteboarding conditions. I had no idea my solution would be automatically validated - I was happy enough to get an in-place O(n) solution. The complete lack of pointers on my part must be what separated me from the cluster of correct solutions at the center.
