When using the LaTeX package url (\usepackage{url} somewhere in the preamble) which tends to give much more nicely formatted web addresses, the following may be preferred:

 @misc{ wiki:xxx,
   author = "Rosetta Code",
   title = "Hofstadter Q sequence --- Rosetta Code{,} ",
   year = "2023",
   url = "\url{https://rosettacode.org/wiki/Hofstadter_Q_sequence?oldid=351205}",
   note = "[Online; accessed 16-January-2025]"
