Sorry, that was yesterday's HN Wordle! (that's the New York Times-acquired wordplay game Wordle, quite the popular wordplay game--just joking that I created a word game of my own)
Useless reflection to ignore below (forewarned!)
I hesitated to post; in the end, the value of the comment was so low, I expected non-wordplay-fans to scroll past and lose nothing, so I left it in the hopes at least one person would find the answer themselves and be pleased about it.
thanks
