IMHO, I would respectfully disagree. K&#x2F;Q canbe used for all manner of software systems.<p>PageRank can be done in a few lines of code - with clarity approaching the mathematical description.<p>The solutions to the Advent of Code (<a href="http:&#x2F;&#x2F;adventofcode.com&#x2F;" rel="nofollow">http:&#x2F;&#x2F;adventofcode.com&#x2F;</a> and <a href="http:&#x2F;&#x2F;kparc.com&#x2F;advent&#x2F;ad.k" rel="nofollow">http:&#x2F;&#x2F;kparc.com&#x2F;advent&#x2F;ad.k</a>) are readily expressed&#x2F;solved in 
k&#x2F;Q.<p>That said, it excels above other languages&#x2F;systems at systems like real-time trading.
